Abstract

A four-section CO2 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 58 W cm−3 corresponding to an efficiency of 2%.
