Tube solid-state laser

摘要: An improved tube solid-state laser (SSL) is provided utilizing diode pumping, microchannel cooling, optics, and/or new coating and bonding processes. In one example, an amplifier module for the SSL includes a of gain material, first substrate second including microchannels adjacent interior exterior surface tube, respectively, plurality bars arranged to substrate. Advantageously, thermal lensing effects, birefringence, bifocussing, alignment problems associated with typical SSLs are eliminated or reduced while providing high beam quality average power levels.
