A Q-switch CW chemical HF laser

An experimental study was carried out of pulse-periodic (rap-rate) operation of a CW chemical HF laser with optomechanical up to 10 3 Hz Q -switched cavity. Output pulse power shown increases at the experimental conditions no less than five-fold through the frequency region of 17-250 Hz. Average power of the rap-rate output reduced considerably comparatively to the same of CW mode operation, but shoot up with growing of the modulation frequency (in the same frequency region) faster than peak pulse power. It were discussed the possible causes of experimental and calculation characteristics differences of laser.
