<title>Four-channel structures 2x2 for selected gas lasers</title>

Abstract

Four-channel structures in form of the second rank 2x2 matrix were investigated. For CO2 lasers we applied phaselocking techniques. He-Ne and He-Xe lasers were built as independent four-channels and optimized for their output power.

“…In this case the pulse regime of the laser source is important. To build such a source we proposed making use of the advantages of rf discharge and a four channel structure of active medium [13]. In the article, we report on the practical realization of that proposal and the preliminarily results of optimization.…”

“…If we would like to use its two lines from the infrared range, e.g. 3.3922 m and 3.3912 m for μ μ remote detection of methane on distances up to 100 m, it is important to increase the laser power to 40 mW [12]. Although on the market there are lasers offered with power of 10-20 mW (at a length of 1-2 m), however their dimensions and weight are not encouraged [3].…”
