On the tuning range of a CW double-discharge Pyrex waveguide12C16O2laser

Abstract

A double-discharge, Pyrex waveguide laser has been built in order to perform infrared spectroscopy studies in the region of lambda =10 mu m. This simple device provides at least 60 laser emission lines with widths from about 200 to about 700 MHz with a typical power output of 150 mW on each of two beams from an angled coupler on the P₂₀ line of the lambda =10.6 mu m band.
