Saturable gas absorber for a 9-microm-band CO2-laser amplifier.
A two-component saturable gas absorber composed of formic acid and SF(6) in separate cells has been successfully used as an isolator in a TEA-CO(2)-amplifier chain for amplifying several 9-microm-band transitions. This isolator suppressed all amplifier self-oscillations in both the 9- and 10-microm bands and was saturated at intensities over 1 MW cm(-2) by 130-nsec, 9-microm band pulses.
