LASER WITH FREQUENCY-CHANGED RADIATION Russian patent published in 1994 - IPC

FIELD: different branches of science. SUBSTANCE: this laser is designed for use where spectrally clear frequency-changed radiation is required including spectral equipment. Laser includes wide-band amplification medium, resonator composed of diffraction grating, mirrors and prism beam expander. Its first prism enables radiation spatially disintegrated into spectrum with the aid of diffraction grating and diaphragms in the way of clear spectral radiation passing after diaphragms through same amplification medium as wide-band radiation to be brought out. EFFECT: improved quality of spectral radiation. 1 dwg
