LASER RETUNABLE SOURCE OF MONOCHROMATIC RADIATION Russian patent published in 1994 - IPC

FIELD: spectrometry. SUBSTANCE: generator of retunable radiation has several retunable lasers mounted on common base with different ranges of retunable wave lengths each provided with individual amplifying medium and pair of mirrors. Each of them can take up two rigorously fixed positions and is fitted with electromagnetic drive and magnetic locator of these positions. All electromagnetic drives are coupled to switching device. For control over position of mirrors each retunable laser only in position of corresponding pair of mirrors is optically coupled with pumping laser and its output beam is matched with direction of output of beam of source. In the other position of mirrors this laser is brought out of optical coupling with pumping laser and output of source. EFFECT: improved operational stability. 2 dwg
