Abstract

A simple hot-cell-free 4.3-μm CO2 laser with longitudinal d.c. discharge is described and the results of its parametrization are presented. It is shown that for effective operation of the 4.3-μm (10° 1-10°0 band) CO2 laser, use of active mixtures containing 4 to 5% of carbon dioxide with ∼20% nitrogen is needed. The laser is mechanically Q-switched producing peak powers in excess of 60 W with a pulse duration of 300 ns FWHM. The 4.3-μm laser is easily tunable and operates on the P and R branches of the 10°1-10°0 band of CO2. The peculiarities of spectral performances are discussed.
