Stable high repetition rate, single-frequency Q-switched operation via feedback suppression of relaxation oscillation
Stable, single-frequency, operation of a Q-switched laser requires initial establishment of a stable prelase, free from relaxation oscillation. Relying on natural decay of oscillation limits repetition rates and hence average power. Using feedback suppression of relaxation oscillation, a Q-switched...

Summary: | Stable, single-frequency, operation of a Q-switched laser requires initial establishment of a stable prelase, free from relaxation oscillation. Relying on natural decay of oscillation limits repetition rates and hence average power. Using feedback suppression of relaxation oscillation, a Q-switched Nd:YAG laser has operated single-frequency reliably at repetition rates up to 25kHz, with 88% of available cw power extracted. |
