Book excerpt: During the interim period of this bridging contract, we have continued to work on the development of high-power cw diode-laser-array-pumped solid-state lasers. Towards that end, we have built lower power lasers in order to test individual components needed for the high-power laser, specifically we have built a 1 watt ring laser and a 5 watt slab laser. The 1 watt laser was used to study the injection locking process while assembling all the necessary electronics. We have demonstrated that it is possible to injection lock a diode- pumped laser using a single piezo-mounted mirror due to the lower intrinsic laser noise compared to an arc-lamp-pumped system. This allows us to optimize the injection locking servo loop and build a more stable locking system. The 5 watt laser was used as a test bed to find a practical way to mount the slab laser while minimizing the losses that occur at the total internal reflection (TIR) points in the slab. After trying many different means of protecting the TIR surfaces, we found that a new product from DuPont, Teflon AF 1600, has all the properties needed to provide a low loss protective coating. Using this material, the laser had a cavity loss of below 2%, which allowed for efficient operation of the laser in a side-pumped design. This laser produced 5 watts of output power with a slope efficiency near 20%.

This book was released on 1993 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three years we have made substantial progress toward the goal of a fiber coupled, diode laser pumped 1OOW cw Nd:YAG minislab laser. We have diode pumped a 1W ring cavity laser and have operated it in a single frequency. We have diode pumped a testbed minislab Nd:YAG laser using fiber coupled diode laser bars and generated 5W of cw, TEMoo mode output power. We have designed and are implementing a 5OW cw minislab Nd:YAG laser to be pumped by 25 diode laser bars coupled through optical fibers. We plan, in the second phase of this program, to achieve the 1OOW cw output power level in a minislab Nd:YAG laser approach proposed as the goal of this research program In addition, we have demonstrated single frequency control of a high power Nd:YAG laser oscillator by injection locking; have frequency stabilized Nd:YAG oscillators by locking to high finesse Fabry Perot resonators; have absolutely stabilized Nd:YAG to one part in 10 to the -13th power by locking to iodine; have frequency converted Nd:YAG by second harmonic generation to 11.2W of cw TEMoo mode green output; have demonstrated the first cw 2 microns OPO in lithium niobate; and have demonstrated the first cw singly resonant OPO with 2W of output in a single frequency in KTP.

This book was released on 1997 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of this program were: development of high-power, cw diode-laser-array-pumped, Nd:YAG lasers, and efficient nonlinear frequency conversion of their output. Two minislab laser heads constructed as a single high power dual-head oscillator (96W, multi-mode) were operated separately to support Q-switched and cw nonlinear frequency conversion studies and single-frequency injection-locking studies and the start of cw amplifier research. A cw singly resonant optical parametric oscillator (SRO) utilizing bulk periodically poled LiNbO3 (PPLN) for tunable mid-IR radiation using the Q-switched laser as the pump was developed, and SHG output at 532 nm was increased from 800 mW average power (15 KHz rep rate) to 1300 mW average power (8.4 KHz rep rate). Coherent laser radar with high-power, high-coherence sources was pursued through a highly-coherent master oscillator cw power amplifier approach. We operated one laser head as a (1OW TEM00) oscillator and the second laser head as a triple-pass amplifier achieving 26 W TEM00 output. More extensive experiments on cw diode-laser pumped laser amplifiers for high-power, high-coherence sources were carried out to test the ability of theoretical modeling to predict amplifier output power.

This book was released on 2009 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main program objective was the development of a kilowatt class, cw Nd:YAG diode-laser-pumped solid-state laser (DPSSL) with quantum noise limited amplitude and phase, 24by7 operation capability and the ability to be repaired while in operation. The approach was a master-oscillator power-amplifier (MOPA) laser utilizing a series of zig-zag slab power amplifiers stages. We developed fiber amplifiers at the 200W level to generate power with high optical efficiency that can effectively extract energy from the power amplifier slabs. We also worked on the generation of high average power visible light by developing nonlinear optical materials with large apertures, low photo-refraction and minimal visible induced infrared absorption. The second objective was to develop a 1 joule, pulse-modulated, diffraction limited MOPA laser with less than 1 MHz line-width. A follow-on objective was frequency conversion to 1.5 or 2.0 microns for remote sensing applications. We demonstrated Yb:YAG slab lasers pumped with high brightness laser diodes. Supporting this project was the development of laser diodes operating in the 1.5 micron region for pumping of erbium doped laser hosts, and the synthesis of new low-loss polycrystalline laser host materials for in-band pumping into the upper laser level to improve the laser efficiency at eye-safe wavelengths. We developed orientation patterned Ga-As to frequency convert high peak power 1-micron radiation to eye-safe wavelengths in the mid-infrared for defense applications. The third objective, power scaling and determining the potential for phase-locking of ultra-fast laser systems for a wide range of sensing and machining applications, was demonstrated as well.

Download or read book Efficient Nonlinear Conversion of Laser Diode Pumped Miniature Solid State Laser Sources written by and published by . This book was released on 1989 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program has dealt with the development of efficient and compact sources of visible laser light based on the nonlinear optical conversion of the outputs of diode pumped solid state lasers. Intracavity frequency doubling, frequency doubling of continuous wave single frequency nonplanar ring Nd:YAG lasers in external resonant cavities and single pass doubling of diode pumped Q-switched lasers were studied. Nonlinear materials including lithium diffused lithium niobate, magnesium oxide doped lithium niobate and potassium titanyl phosphate were examined. We obtained 45 mW of cw green light from an monolithic externally resonant cavity constructed of MgO:MiNbO3 pumped by a 200 mW single frequency Nd:YAG laser. This doubler was electro-optically locked into resonance with the laser oscillator and maintained at phasematching temperature by a miniature platinum hybrid heater-sensor element and control circuit. Peak powers LiNbO3 over 200 mW in the green were measured with this doubling device when pumped by a single frequency pulsed 500 mW source.

Book excerpt: Advances in High-Power Fiber and Diode Laser Engineering provides an overview of recent research trends in fiber and diode lasers and laser systems engineering. In recent years, many new fiber designs and fiber laser system strategies have emerged, targeting the mitigation of different problems which occur when standard optical fibers are used for making high-power lasers. Simultaneously, a lot of attention has been put to increasing the brightness and the output power of laser diodes. Both of these major laser development directions continue to advance at a rapid pace with the sole purpose of achieving higher power while having excellent beam quality. The book begins by introducing the principles of diode lasers and methods for improving their brightness. Later chapters cover quantum cascade lasers, diode pumped high power lasers, high average power LMA fiber amplifiers, high-power fiber lasers, beam combinable kilowatt all-fiber amplifiers, and applications of 2 μm thulium fiber lasers and high-power GHz linewidth diode lasers. Written by a team of authors with experience in academia and industrial research and development, and brought together by an expert editor, this book will be of use to anyone interested in laser systems development at the laboratory or commercial scale.
