Abstract:
Laser radiation was generated in zinc sulfide crystals by streamer excitation using both transverse and longitudinal systems for coupling out the radiation. The output power was 170 W (T = 77 K) in the first case and 1 kW (300 K) in the second. A study was made of the crystallographic orientation of the streamer tracks in zinc sulfide single crystals containing between 2% and 10% of the hexagonal phase.
