Abstract

A copper vapor laser is developed with intracavity acousto-optic modulator which allows to independently electronically control the laser light components with wavelengths 510,6 and 578,2 nm. The cavity of the laser is an unstable resonator formed by concave spherical mirrors with enlargement coefficient M=40 and an output mirror with a connection hole. The light output parameters were controlled by an acousto-optic modulator put inside the laser cavity between the mirror of less radius and the output mirror. The acousto-optic modulator was a specially built wide-aperture non- collinear paratellurite crystal filter, in which the diffracted light intensity slightly sensitive to the changes of the angle of the light falling onto the acousto-optic modulator, and the diffraction angles coincide for different spectral components.
