TUNABLE LASER Russian patent published in 2005 - IPC

FIELD: laser engineering; tunable lasers.

SUBSTANCE: laser has case accommodating cavity incorporating active medium, output mirror, and spectral-selective element in the form of diffraction grating. Grating set up in bezel is connected through first adjusting mechanism to loose end of moving lever. Other end of the latter is locked in position by means of spherical supports in U-shaped flange connected through second adjusting mechanism to laser case. Loose end of moving lever is kinematically coupled with micrometer screw. Provision for individual and independent adjustment of dispersion plane of diffraction grating and axis of revolution of moving lever, with this position being maintained in the course of operation, ensures steady and reliable functioning of laser under all mechanical and environmental impacts.

EFFECT: enhanced, reliability, reproducibility and precision of wavelength selection.
