Dear Friends,

Looking back on 2019, we are filled with joy, excitement and pride. The year marked not only the 70th anniversary of the founding of the People’s Republic of China and the Chinese Academy of Sciences, but also the 55th anniversary of the founding of the Shanghai Institute of Optics and Fine Mechanics (SIOM).

In 2019, SIOM achieved major scientific and technological progress in many areas, with numerous important results: 1) SIOM achieved the capacity to independently research and develop a fusion-ignition laser driver. It developed its overall design, the technology of key parts, components and materials; and accomplished its system integration; 2) The Shanghai Superintense Ultrafast Laser Facility (SULF) was basically completed in 2019. Its overall operating efficiency has greatly increased to one shot every three minutes, a new world Phone: +86-21-69918461 record for output energy from a titanium-sapphire laser; 3) The Beidou-3 BeiDou Email: [email protected] MEO-21/22 inter-satellite laser link, Gaofen-7 satellite laser, and microgravity test satellite laser were all successfully launched in 2019; 4) SIOM’s laser distance sensor and three-dimensional imaging sensor fiber laser helped Chang'e-4 land Professor SHAO Jianda on the far side of the moon in January, 2019; and 5) SIOM’s multilayer dielectric Research Interest: Optical engineering and high-reflective coating was named best in its category for the fourth time at the optical materials International Laser Damage Competition in September, 2019.

In 2019, SIOM began setting up its Hangzhou Branch, thus actively taking advantage of the opportunity accorded by the National Initiatives of Yangtze River Delta Integration.

SIOM is prepared and looking forward to the new challenges ahead. In 2020, it will usher in a new round of reform and development, focusing on accelerating the development of our Center for Excellence in Ultra-intense Laser Science and building SIOM into one of the top global institutions in laser science and technology.

SIOM must change with the times. However, just as our commitment to the exploration of laser science remains unwavering, we also maintain our commitment to "Better laser, better life."

Let’s join hands to create a beautiful future!

Cordially,

1.Superintense Ultrafast Laser and its Applications

Shanghai Superintense Ultrafast Laser Facility (SULF), with amplified energy of 420 J and compressed duration also known as Xi-He laser facility, contains a 10 PW of 23.3 fs, which is a new world record for the ultra-in- beamline, a 1 PW beamline, and three user experimental tensity and ultra-short laser systems. Six pump lasers platforms. The 10-petawatt ultra-intense and ultrafast with output pulse energy of ~ 100 J and repetition rate laser facility can provide unprecedented extreme and of one shot per 3 minutes were developed and used as comprehensive physical environments of ultra-high pump sources in the 10 PW laser system. Also this year, density, ultra-strong electromagnetic field and ultra-fast the 1 PW laser system with repetitive rate of 0.1Hz and a time scale. nanosecond 300 J Nd:glass laser system have been built

Intense Attosecond Pulses Carrying Orbital Angular Momentum Using Laser Plasma Interactions

G. momentum (OAM) and provide an additional degree of freedom to NATURE COMMUNICATIONS, 2019, 10:5554 beams of coherent light. While OAM beams can be readily derived from https://www.nature.com/articles/s41467-019-13357-1 Gaussian laser beams with phase plates or gratings, this is far more challenging in the extreme ultra-violet (XUV), especially for the case of high XUV intensity. Here, we theoretically and numerically demonstrate that intense surface harmonics carrying OAM are naturally produced by the intrinsic dynamics of a relativistically intense circularly-polarized Gaussian beam (i.e. non-vortex) interacting with a target at normal incidence. Relativistic surface oscillations convert the laser pulses to intense XUV harmonic radiation via the well-known relativistic oscillating mirror mechanism. We show that the azimuthal and radial dependence of the harmonic generation process converts the spin angular momentum of the laser beam to orbital angular momentum resulting in an intense attosecond pulse (or pulse train) with OAM.

08 08 http://english.siom.cas.cn/ New Optical Manipulation of Relativistic Vortex Cutter

A new relativistic vortex cutter driven by the Laguerre-Gaussian (LG) mode is carried out for the first time in three-dimensional particle-in-cell simulations. Studies show that the electric fields periodically concentrate and emanate l within every laser wavelength for the reflected circularly polarized LG p (p=0 , σ l=1 , z=−1 ) laser, which works just like a vortex cutter, resulting in a relativistic ultrashort collimated electron cluster with a constant period in space. A single particle model is given and verifies that the cluster formation has a close relation with the parameters of orbital angular momentum (l ) and σ spin angular momentum ( z ). Such a relativistic vortex cutter potentially can be applied for the accelerator, generating high-flux particle and coherent radiation sources, and so on.

Two-Photon Pumped Amplified Spontaneous Emission and Lasing from Formamidinium Lead Bromine Nanocrystals

However, their as an excellent optical gain medium. The strong temperature-tolerent ASE development on nanolaser application have rarely been explored, action with a high characteristic temperature of 308 K indicates the especially the up-conversion lasing performance. Here, the two-photon weak requirements of heat management of FA-based devices. Finally,

These colloidal FAPbX3 NCs exhibit high-quality low threshold of ~310 µJ/cm . Our findings suggest that FAPbX3 NCs cubic phase and tunable bright emission (from 433 to 667 nm). By can act as excellent gain media for high-performance upconverted tuning the ratio of the surface organic ligands, the morphology of nanolasers toward optoelectronic application.

FAPbBr3 NCs can be transferred from quantum dots to nanoplatelets, consequently the emission can be tuned in 520–542 nm.

High Power, Microjoule-Level Diffraction-Limited Picosecond Oscillator

Based on Nd:GdVO4 Bulk Crystal

1.2 µJ pulses with average power of 9 W were directly generated from a

passively mode-locked picosecond oscillator based on a Nd:GdVO4 bulk crystal. Short cavity operation in continuous wave and mode-locking regimes was conducted first to confirm the resonator performance and proper alignment. With a carefully calibrated q-preserving multi-pass cell inserted into the laser cavity, the cavity length of the original short cavity was extended while the mode-matching condition was maintained fairly well. Compared with the short cavity, nearly fivefold energy enhancement was achieved while the diffraction-limited beam quality was undisturbed. To the best of our knowledge, this is the highest output power ever produced from a mode-locked oscillator based on a single bulk crystal at a repetition rate below 10 MHz without cavity dumping.

The method is given theoretically and verified experimentally. Under the condition of fiber nutation frequen- cy is 2000Hz and nutation radius is 1.1um, the experimental verification results in our interested range of signal light power (1nW-10nW) meet our design requirements. The receiving field of view (FOV) of tracking system is more than 300urad, and the closed-loop tracking bandwidth (−3dB) is about 115 Hz. When the boresight error is fixed at 80urad, the real calculation error is less than 10%. The closed-loop performance of tracking system is insensitive to the change of signal light power. Our coherent tracking system is of great significance to the inter-satellite beaconless laser communication.
