Ti:Al2O3 laser pumped by a copper vapor laser

Abstract

Comparative study has been performed of the influence of pumping by two separated wavelengths λ equals 520.6 and λ equals 578.2 nm from a copper vapor laser on the output characteristics of a Al2O3:Ti3+ laser. It is shown that the pumping by the long-wave spectral component of the copper vapor radiation is comparable in efficiency with pumping at the wavelength for the shortwave part of the Al2O3:Ti3+ laser generation range. The differential efficiency 26% in the center of the amplification line of the Al2O3:Ti3+ laser at the wavelength 770 nm is obtained.
