Features of emission from a submillimeter laser under intense optical pumping

The emission of a submillimeter laser pumped by a high-power (up to {approx} 1 kW) CO{sub 2} laser is studied. It is found that lasing of CH{sub 2}F{sub 2} molecules saturates at the pump power {approx}350 W. A delay of submillimeter lasing depending on the gas pressure in the active medium and the...

Description
Summary:The emission of a submillimeter laser pumped by a high-power (up to {approx} 1 kW) CO{sub 2} laser is studied. It is found that lasing of CH{sub 2}F{sub 2} molecules saturates at the pump power {approx}350 W. A delay of submillimeter lasing depending on the gas pressure in the active medium and the pump intensity is observed. The possibility of a rapid tuning (in about 1 ms) of the submillimeter laser emission by scanning the emission from the CO{sub 2} laser is demonstrated experimentally.
