Correction of wavefront distortions and depolarization in solid-state laser amplifiers

Results are reported of the study of systems averaging the azimuthal inhomogeneities of gain and suppressing aberration and polarization wavefront distortions formed in active amplifying elements of a repetitively pulsed Nd:YAG laser. A twofold decrease of depolarization in the amplified radiation was obtained. An optimum filling of active elements due to correction of radiation distortions in the near field was realized.

Powerful multichannel Nd:glass laser tunable in wide spectral range

The powerful tunable laser with high output energy is needed for laser spectroscopy, laser chemistry, biology, medicine and other appi icat ion. The result of design of the powerful Nd: glass laser set -up ut ii iz ing process of harmonic generation, optical parametric oscillation, parametric ampl if icat ion under the injection of the seeding radiat, st iinulated Raman scattering all owing to span completely through the spectral range from 1.3 to 0. with the output energy of several J are reported.
