Abstract

The paper presents the experimental results on how the tube bore of copper bromide laser influence the gain radial distribution. A pair of copper bromide lasers in an oscillator- amplifier configuration was operated to measure and compare the small-signal gains of different laser tube bores. The gain radial distributions were measured in different size of amplifier tube bores. It was shown that, by changing the amplifier tube bore, the gain radial distribution was changed, similar to that of the temperature profile, but the average of radial gains through cross-section are the same in different laser tube bores.

Highlights

Copper bromide lasers (CBL), as a kind of halide lasers, can produce the wavelengths of 510.6 nm and 578.2 nm in visible region, similar to that of copper vapor lasers (CVL); the CBL has the same attractive applications of CVLs in different areas of science and technology
The important advantage of a CBL compared with the CVL is operating at lower temperature (~510 ̊C) and having higher beam quality, which is better suited to many applications such as brightness amplifiers in visualization system-laser monitors (Fedor Aleksandrovich Gubarev & Klenovskii, 2016; Kulagin, Torgaev, & Evtushenko, 2020)

Summary

Introduction

Copper bromide lasers (CBL), as a kind of halide lasers, can produce the wavelengths of 510.6 nm (green) and 578.2 nm (yellow) in visible region, similar to that of copper vapor lasers (CVL); the CBL has the same attractive applications of CVLs in different areas of science and technology. Some works have been studied on spatial-temporal gain distribution on CBL The independencies of the amplifying parameters of CBL on the different amplifier tube length with identical diameter has been investigated, individually.
