Cryolaser: Innovative cryogenic diode laser bars optimized for emerging ultra-high power laser applications

摘要

“Cryolaser” diode laser designs exploit the improvement in semiconductor material properties at sub-zero temperatures to increase efficiency and power. Optimized single 9xx-nm laser bars demonstrate record peak pulse energy of 2 J (1.7 kW, 1.2 ms, −50°C).
