Direct Narrow line Tuning of a High Power CO2 Pump Laser

摘要

A high power, narrow line CO₂ pump laser for submillimeter laser applications has been constructed by direct grating tuning of an unstable resonator oscillator and injection tuning to a single longitudinal mode. The oscillator produces 200-400 joule pulses on the 9R(22) line with a line width of less than 20 MHz.
