摘要

Over the past decade, solid-state lasers have demonstrated remarkable power in scaling. To a large extent, the emergence of solidstate lasers as competitive high-power devices is due to the availability of highly efficient (60 percent), high-power (100 W), low-cost ($10/W mounted) laser diode bars. This chapter presented an overview of the approach, history, and current state of scaling Nd:YAG ceramic ThinZag lasers to significant power levels using a single-aperture power oscillator architecture. These lasers are compact and scalable to 100 kW and higher power levels. Recently average power levels in excess of 100-kW output were achieved in final government testing of the JHPSSL program. A critical issue, as with all very high power solid-state lasers, is achieving excellent beam quality at the highest powers.
