Laser-induced damage threshold of ZnGeP2 crystal for (sub)picosecond 1-μm laser pulse

Laser-induced damage threshold (LIDT) was measured for a ZnGeP2 crystal 16 exposed to 0.3-9.5 ps 1030-nm laser pulses. Single-pulse LIDT fluence was ~0.22 J/cm2 for 17 the laser pulse widths of 0.3-3.5 ps and increased till 0.76 J/cm2 for 9.5-ps pulses. Multi-pulse 18 LIDT fluence for 0.3-ps pulses...
