Quasi-cw 20-W tunable 1-sec pulse CO/sub 2/ laser for optical pumping
Journal Article
·
· Appl. Opt.; (United States)
A four-section CO/sub 2/ laser is described which can produce 20 W in fundamental mode during a 1-sec pulse with a frequency tuning range of +- 300 MHz. It operates at 200-Torr pressure using sonic axial flow to inhibit the discharge column from filamenting. The input power density is 598 W cm/sup -3/ corresponding to an efficiency of 2%.
