ACTIVE MEDIUM OF LASER Russian patent published in 1995 - IPC

Abstract SU 1407368 A1

FIELD: quantum electronics. SUBSTANCE: active medium of laser based on monocrystal LiF(F2F+3

) has concentration of working centers corresponding to absorption factors at wave length 460 mm within interval 27-37 cm-1 for F+3
-centers, 33-99 cm-1 for F2-centers and absorption factor of accompanying F3-centers lies within interval 0.01-2.3 cm-1 at wave length 380 mm. Laser active medium gives possibility to generate simultaneously on two types of color centers (F2, F+3
) with expansion of spectral region of generation to 516-750 mm. EFFECT: reduced threshold of generation of F+3
-centers with simultaneous increase of optical stability of F2-centers. 2 dwg, 1 tbl
