An optical amplifier that converts energy into highly concentrated beams of light by stimulated emission of Light photons (light particles) from excited matter. The unique properties of laser light enable more powerful, precise and flexible processing within numerous industries and applications. Amplification by (1) Optical Resonator Stimulated Emission of (2) Gain Medium (6) Laser Beam Radiation (4) High Reflector (3) Energy Source (5) Output Coupler How a Laser Works A laser consists of: (1) an optical resonator, typically two mirrors between which a coherent light beam travels in both directions; (2) a gain medium material within the resonator with properties that allow light amplification by stimulated emission; and (3) an energy source of light or electric current that excites atoms in the gain medium, known as pumping. Light in the gain medium travels back and forth between the two mirrors – the (4) high reflector and the (5) output coupler – being amplified each time. The output coupler is partially transparent, allowing some of the photons or (6) laser beam to exit. Types of Lasers Lasers are often categorized by the type of gain medium (gas, crystal, fiber, semiconductor) but are also distinguished according to: (1) wavelength of operation

    Tutorial: Fiber-Coupled Laser Diode Basics

    Tutorial: fiber-coupled laser diode basics Fiber coupled laser diodes: this tutorial provides an overview of the technical properties of fiber- coupled laser diodes. The various laser diode families such as DFB laser diodes or multi-emitter high power laser diodes will be described in this tutorial. I. Introduction Laser diodes are everywhere today. They are the simplest element to convert electrical power into laser power. Laser diodes are based on several semiconductor assembled materials (GaAs, InP or other more complex structures like GaN). Singlemode laser diodes are low power laser diodes (typically <1W) whereas multimode laser diodes are much higher power devices (typically >10 W up to several kW). II. Optical fibers: Two types of active fibers are commonly used to couple the light coming in from a laser diode: • Single mode fibers have a core of typically a few µm (for example ~6 µm around a wavelength of 1 µm, and 9 µm around a wavelength of 1.5 µm) • Multimode fibers are larger diameter fibers that can handle a much higher level of optical power. Standard versions have typically 62, 100, 200, 400, 800, or even > 1000 µm core diameter. For example, the smaller the diameter, the easier it is to focus to a small spot the light coming from the fiber with a lens or a microscope objective. Figure 1: Principle of a single mode or multi-mode fiber. The fiber core is much larger when considering a multimode fiber. • Polarization Maintaining fibers: Singlemode laser diode can be either standard (SMF) or Polarization maintaining (PM). In the latter, the optical fiber has a special clad structure which allows the maintenance of the polarization of light all along the fiber length.

Additionally, a narrow (<0.5nm), tunable (30nm) cw operation near 2.09 µm, will be shown. © 2011 Optical Society of America OTIC codes: (140.3460) Lasers, (140.3070) Infrared and far-infrared lasers. 1. Introduction Continues-wave 2 µm laser show applications in the ‘eye-safe’ wavelength range, e.g., laser material processing, laser welding of transparent plastic materials as well as laser surgery or therapy. Furthermore, a pulsed-mode operation of a 2 µm laser opens up the mid-infrared region via pumping of an optical parametric oscillator based on nonlinear crystals like zinc germanium phosphide (ZnGeP2) or orientation- patterned GaAs to efficiently produce radiation in the 3 µm – 12 µm spectral range. For gas monitoring or remote sensing, the tunable 2 µm laser can be operated in the wavelength range of CO2 molecules to detect footprints of their vibrational bands [1]. The larger emission cross section of the Ho3+-system at 2.09 µm compared to Tm3+-systems makes the Ho:YAG thin disk laser concept with its inherent low gain per pass in a multiple pump pass concept [2] 5 attractive for the generation of high power in cw- or pulsed-mode operation.

    Modelocking of a Thin-Disk Laser with the Frequency-Doubling Nonlinear-Mirror Technique

    Vol. 25, No. 19 | 18 Sep 2017 | OPTICS EXPRESS 23254 Modelocking of a thin-disk laser with the frequency-doubling nonlinear-mirror technique * F. SALTARELLI, A. DIEBOLD, I. J. GRAUMANN, C. R. PHILLIPS, AND U. KELLER Institute for Quantum Electronics, ETH Zurich, 8093 Zurich, Switzerland *[email protected] Abstract: We demonstrate a frequency-doubling nonlinear-mirror (NLM) modelocked thin- disk laser. This modelocking technique, composed of an intracavity second harmonic crystal in combination with a dichroic output coupler, offers robust operation decoupled from cavity stability (as in semiconductor saturable absorber mirror (SESAM) modelocking) combined with an ultrafast saturable loss and high modulation depth (as in Kerr-lens modelocking (KLM)). With our NLM diode-pumped Yb:YAG thin-disk laser we achieve 21 W of average power at 323-fs pulse duration, which is an order of magnitude shorter than the previously obtained duration with the same technique in bulk lasers. Using these first results, we present a theoretical model for the NLM technique, which accurately predicts its loss modulation properties and the shortest achievable pulse duration without relying on any fitting parameters. Based on this simulation, we expect that the NLM technique will enable thin-disk lasers with average power of more than 100 W, with potentially sub-200 fs pulses. This could potentially solve the pulse duration limitations with SESAM modelocked Yb:YAG thin-disk lasers without imposing strong cavity stability constraints such as in KLM. © 2017 Optical Society of America OCIS codes: (140.0140) Lasers and laser optics; (140.4050) Mode-locked lasers; (140.7090) Ultrafast lasers; (190.7110) Ultrafast nonlinear optics.

    Few-Cycle Pulses Amplification for Attosecond Science Applications: Modeling and Experiments

    FEW-CYCLE PULSES AMPLIFICATION FOR ATTOSECOND SCIENCE APPLICATIONS: MODELING AND EXPERIMENTS by MICHAËL HEMMER M.S. Engineering Ecole Nationale Supérieure de Physique de Marseille, 2005 A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the College of Optics and Photonics at the University of Central Florida Orlando, Florida Spring Term 2011 Major professor: Martin Richardson © 2011 Michaël Hemmer ii ABSTRACT The emergence of mode-locked oscillators providing pulses with durations as short as a few electric-field cycles in the near infra-red has paved the way toward electric-field sensitive physics experiments. In addition, the control of the relative phase between the carrier and the pulse envelope, developed in the early 2000’s and rewarded by a Nobel price in 2005, now provides unprecedented control over the pulse behaviour. The amplification of such pulses to the millijoule level has been an on-going task in a few world-class laboratories and has triggered the dawn of attoscience, the science of events happening on an attosecond timescale. This work describes the theoretical aspects, modeling and experimental implementation of HERACLES, the Laser Plasma Laboratory optical parametric chirped pulse amplifier (OPCPA) designed to deliver amplified carrier-envelope phase stabilized 8-fs pulses with energy beyond 1 mJ at repetition rates up to 10 kHz at 800 nm central wavelength. The design of the hybrid fiber/solid-state amplifier line delivering 85-ps pulses with energy up to 10 mJ at repetition rates in the multi-kHz regime tailored for pumping the optical parametric amplifier stages is presented.

    Characterization and Modeling of a High Power Thin Disk Laser

    Characterization and Modeling of a High Power Thin Disk Laser by Omar R. Rodriguez B.S. University of Central Florida, 2008 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the School of Electrical Engineering and Computer Science in the College of Engineering and Computer Science at the University of Central Florida Orlando, Florida Summer Term 2010 Major Professor: Martin C. Richardson ABSTRACT High power lasers have been adapted to material processing, energy, military and medical applications. In the Laser Plasma Laboratory at CREOL, UCF, high power lasers are used to produce highly ionized plasmas to generate EUV emission. This thesis examines the quality of a recently acquired high power thin disk laser through thermal modeling and beam parameter measurements. High power lasers suffer from thermally induced issues which degrade their operation. Thin disk lasers use an innovative heat extraction mechanism that eliminates the transverse thermal gradient within the gain medium associated with thermal lensing. A thorough review of current thin disk laser technology is described. Several measurement techniques were performed on a high power thin disk laser. The system efficiencies, spectrum, and temporal characteristics were examined. The laser was characterized in the far-field regime to determine the beam quality and intensity of the laser. Laser cavity simulations of the thin disk laser were performed using LASCAD. The induced thermal and stress effects are demonstrated. Simulated output power and efficiency is compared to those that have been quantified experimentally. ii To my family. iii ACKNOWLEDGMENTS The culmination of this thesis represents a step in my life which I could not have ac- complished without the help of many people.
