2 OPIC 2019・22-26 April, 2019 Welcome to OPIC 2019

Kazuo Kuroda Yoshiaki Kato Shuji Sakabe Co-Chair Co-Chair Chair OPIC 2019 Organizing Committee OPIC 2019 Organizing Committee OPIC 2019 Steering Committee Professor, Utsunomiya University Professor, GPI Professor, Kyoto University

OPIC (Optics and Photonics International Congress) and OPIE (Optics and Photonics International Exhibition) are the international forums to present and discuss the most up-to-date R&D and industrial activities in optics and photonics in the world and to exchange thoughts on the role of optics and photonics in our future society. The first OPIC/OPIE was started in 2012 under the organization of the Optics and Photonics International Council (OPI Council) and has been held each year in Yokohama.

The Nobel Prize in Physics in 2018 was chosen from the laser science field deeply related to the OPIC topics; Prof. Arthur Ashkin, for the optical tweezeres and their application to biological systems, and Profs. Gerard Mourou and Donna Strickland, for their method of generating high-intensity, ultra-short optical pulses (chirped pulse amplification). Both have been contributing greatly to the fields of biology, chemistry and physics. The communities related to this OPIC are pleased that the award winners come from the target fields of this congress. The OPIC organizer and participants will be delighted to celebrate the winning of the three professors. At the beginning of the plenary session, Chris Barty (Congress chair) and Takeshige Omatsu (OMC Chair) will give short presentations on the Nobel Prize Laureates.

At the plenary session of OPIC 2019, four distinguished speakers will present on the following hot topics; ‘Recent advances in SESAM-modelocked high-power thin disk lasers’, ‘The 10 PW and 100 PW lasers: Paving the way for exploring the next frontier of high field physics’, ‘A billion times brighter: An overview of the revolution underway in X-ray science’, and ‘Quantum neural network - coherent Ising machine, XY machine and recurrent neural network’. OPIC 2019 is composed of 14 professional conferences. We are very pleased to welcome OPTM 2019 (Optical Technology and Measurement for Industrial Applications) and OWPT 2019 (Optical Wireless and Fiber Power Transmission Conference) to OPIC this year. The OPI Council sincerely appreciates the authorized support of the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the Ministry of Economics, Trade and Industry (METI), the Ministry of Agriculture, Forest and Fishery (MAFF), the Ministry of Health, Labor and Welfare (WHLW), the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and Keidanren (Japan Business Federation). We appreciate cooperation with the societies and agencies in Japan, USA, Germany, Taiwan, and Korea. Also we would like to thank the founding organizations and companies for their strong support of OPIC 2019.

Recent advances in SESAM-modelocked high-power thin disk lasers

Prof. Ursula Keller ETH Zurich, Physics Department, Switzerland [email protected]

Abstract Ultrafast thin-disk-laser (TDL) oscillators [1]

Average output power for SESAM-modelocked and an Yb:YAG TDL oscillator delivering a record-high Kerr-lens modelocked (KLM) thin-disk oscillators, labels report the pulse energy. The presented result with 350 W represents the 350-W average power with 940-fs, 40-µJ pulses highest power achieved so far by any ultrafast oscillator. Schematic exploiting vacuum operation, multiple passes on the of the cavity design. The laser is placed inside a vacuum chamber to minimize nonlinearities from air and the disk’s overall thermal disk, and large pump spot. Power scaling toward 500 W lensing; Laser diagnostics: intensity autocorrelator trace and, in the 2 appears feasible [5]. When operated in air the pulse inset, optical spectrum (red dashed lines are sech fits). energy is limited by the nonlinear refractive index of To obtain this new result we made several the intracavity air, which leads to a strong self-phase improvements in the laser design. The thin-disk modulation (SPM). We used the negative phase shift technology offers power-scaling by increasing the achievable from cascaded-χ(2) nonlinearities (CQN), i.e. pump spot size on the disk, which enables higher pump a second-harmonic generation (SHG) crystal operated powers while keeping the pump intensity below the in the phase-mismatched regime, to cancel the positive damage threshold. However, the corresponding phase shift from air. Using this technique, we were able increase in laser mode size leads to an increased to obtain 210 W of output power at 780-fs pulse sensitivity to the disk’s thermal lensing, which ultimately duration and 19.2-µJ pulse energy in air [6]. limits the achievable output power with an optimal beam quality (M2<1.1). This hinders pulse formation, Content eventually preventing modelocking of the laser. We TDL oscillators currently achieve the highest tackled this challenge leveraging the fact that by output power and pulse energy of any ultrafast laser operating the laser in vacuum the disk’s overall thermal technology [1-4]. Here, we present a new record lensing is reduced [7]. Additionally, vacuum operation average-output-power result for any modelocked removes the optical nonlinearities due to the air, oscillator. We demonstrate 350 W with 940-fs pulses at simplifying the nonlinearity management necessary for the output of an Yb:YAG thin-disk oscillator soliton pulse formation in such oscillators. Moreover,

18 OPIC 2019・22-26 April, 2019 OPIC 2019 Plenary Sessions we employed a cavity design with a multi-pass arrangement on the disk. This leads to a large round- trip gain, allowing large output-coupling rates. Thereby, we could reduce the intracavity power for a given Plenary output power, alleviating the stress on the intracavity components, particularly on the SESAM. The laser oscillator (Fig. 1) includes a 100-µm thick, Figure 2. Overview of the GDD used in TDLs with respect to their output pulse energy. Our result, thanks to the use of cascaded χ(2) 10-at.% doped Yb:YAG disk, contacted on diamond nonlinearities, overcomes the trade-off in GDD versus pulse (TRUMPF). The thin-disk is pumped via a 44-pass thin- energy typical of ‘Standard TDL’, lying in a region previously accessible only through vacuum systems.

The key characteristics of XFEL radiation are: ultrashort pulse length (currently 0.2 to ‘A billion times brighter’: An overview of 200 fs), high transverse coherence and controllable the revolution underway in X-ray science longitudinal coherence, extreme brightness (typically 109 to 1010 times higher than a synchrotron), and the ability to scan wavelength (roughly 0.05 to 5 nm). As such, XFELs are well suited to deploying a wide array of imaging, scattering and spectroscopic tools for studying the dynamics of matter at the molecular scale – providing chemical specificity with atomic resolution, on the timescales that molecular bonds are formed and evolve.

Sponsored by SPIE.

Conference Chair Toyohiko Yatagai Center for Optical Research and Education, Utsunomiya University

On behalf of the organizing committee and program committee, it is our great pleasure that the 5-th Biomedical Conference Imaging and Sensing Conference in Yokohama is going to open successfully, within the framework of the OPTICS & PHOTONICS International Congress (OPIC 2019). In biomedical optics and photonics, optical tools are employed for the understanding and treatment of diseases, from the cellular level to macroscopic applications. At the cellular level, highly precise laser applications allows the manipulation, operation or stimulation of cells, even in living organisms or animals. Optical microscopy has been revolutionized by a thorough understanding of the different markers and their switching behavior. Marker-free microscopy, like CARS, SHG or THG-microscopy is spreading into multiple biological and clinical imaging applications. OCT is continuously broadening its clinical applicability by even higher resolution, higher speed and more compact and the use of Doppler and polarization sensitivity for functional imaging. In the field of optics and photonics, biomedical imaging and sensing areas are most quickly progressing and expanding. Techniques developed in these areas could bring us great steps in advances of physical, engineering and biological knowledge as well as optics and photonics technology. This conference aims at covering several aspects from the fundamental studies at cellular level to clinical applications of various optical technologies. Finally we hope the 5-th Biomedical Imaging and Sensing Conference contributes to the progress in this field and we hope you enjoy fruitful discussions in the Conference.

Optical Manipulation and Structured Materials Conference 2019 OMC 2019

Sponsored by Optical Wireless Power Transmission Committee, The Laser Society of Japan

OMC 2019 Conference Chair Takashige Omatsu Chiba Univ. [email protected]

Since the first demonstration of an optical tweezer based on optical radiation forces (scattering and gradient forces) created by a tightly focused laser beam, optical tweezers have been widely investigated in a variety of research fields, Conference including biology, physics, and chemistry. In fact, Dr. A. Ashkin was awarded Nobel Prize in Physics, for contributing to a pioneering work of optical manipulation, 2018. Conventional optical tweezers have been mostly adopted to dielectric particles with a dimension range from hundreds of nanometers to tens of micrometers. However, they do not always enable us to efficiently trap metallic particles. In recent years, plasmonic tweezers based on enhanced radiation forces owing to surface plasmon polaritons in metallic nanostructures have been successfully demonstrated to efficiently trap and manipulate both nanosacle-sized dielectric and metallic particles. Also, structured lights, such as higher order Laguerre-Gaussian and Bessel beams carry optical angular momenta, and they provide unique tweezing abilities, for instance, for inducing an orbital motion of the trapped particles without employing mechanical systems. Since 2014, the OMC has successfully collected more than 80 participants from home and abroad. The OMC 2019 conference aims to present and discuss up-to-date scientific subjects, new technologies, and applications related to the fields of optical and plasmonic tweezers, the manipulation of nanostructures, structured optical fields and their satellite topics. We hope that this conference will also facilitate scientific and professional networking as well as scientific inspiration through discussions.
