Abstract
For compact and lightweight LASERs, producing stable output laser beams in adverse environments,such as high-vibration and high-temperature shock is a global problem. A solid-state high-power pulsed LASER is developed in this study. This LASER adopts tightly set six-channel LD pumped configuration and a single-aperture output scheme employs mutual-injection and confinement technic. By applying the method "confining oscillation and amplification", LASER parameters are: 100 mm × 100 mm × 300 mm in block dimension, 1.06μm in wavelength, 10Hz, 9.66J/pulse@0.5ms, beam quality 5mm × 2mrad, energy instability < 2%, and another beam: 3.1J/pulse@8.39ns, beam quality 5 mm × 2.5 mrad. The LASER is compact, lightweight, highly reliable, and with high pulse energy and excellent beam quality, thus allowing long-pulse and short-pulse operations. The developed approach can be potentially used for future applications.
