DESIGN, CONSTRUCTION, AND STUDY OF A Q-SWITCHED CO2-N2-HE GAS LASER.
Abstract
An electrically driven mechanical Q-switch was placed in a CO2-N2-He laser vacuum to eliminate Brewster angle window losses. The resonator length was 179 cm. Laser output was produced at 10.6 microns and 9.6 microns with and without tube cooling. For tube temperatures from 273K. to 183K., laser output at 4.35 microns was found to vary approximately as exp(constant/T to the 3/2 power). Cooling the laser tube to 77K. changed the system to a CO laser. When Q-switched, it produced laser oscillation on 73 lines in the vtov-1 bands of the CO X Sigma+ ground state for 3<or=v<or=17. Cascading of these transitions with approximately a 1 microsec time delay was observed. (Author)
