Wide-band interferometric tuning of a multiatmosphere CO 2 laser
Abstract
We describe the operating characteristics of a compact, frequency tunable, electron-beam-controlled, 15 atmosphere CO 2 laser. Two intracavity Fabry-Perot etalons have been used to obtain laser line narrowing and continuous tuning within the 10.4 μm and 9.4μm bands of the CO 2 gain spectrum. The laser output consists of a 100 nsec pulse (fwhm) with energy up to 100 mJ. The overall laser tuning range is 70 cm -1 and we have measured a laser linewidth of 0.03 cm -1.
