Recent Development of High-Power Visible Laser Sources Employing Solid-State Slab Lasers and Nonlinear Harmonic Conversion Techniques.

摘要

Recent developments in high-power solid-state lasers (Nd:YAG, Nd:glass) have greatly improved both average power capability and beam brightness. This has been a result, to a large extent, of the development of the total-internal-reflection slab-type solid-state laser configuration, which provides a self-compensating mechanism to minimize the thermally induced distortion commonly observed in solid-state lasers. Near diffraction-limited, high peak power, high average power solid-state lasers are ideal pump sources for nonlinear frequency conversions using harmonic generation, stimulated Raman scattering and/or pumping dye laser s for ultraviolet (UV), visible, and infrared (IR) coherent light sources. Continuously tunable coherent sources covering a spectral range from 0.2 microns to beyond 3 microns, using these combined techniques, have been reported. (Author)
