Regenerative CO2 amplifier of a nanosecond pulse train

Abstract

Regenerative amplification of a nanosecond pulse train in the 50 L active volume CO2 laser has been investigated both numerically and experimentally. The area in which RA takes place was determined when varying the injected radiation parameters. The nanosecond pulse train utilization as an injected radiation instead of a monopulse was shown to significantly broaden the injection time “window” and to enable variation of an individual pulse time structure in the output train.
