PULSED SOLID-STATE LASER WITH RADIATION WAVELENGTH CONVERSION ON STIMULATED RAMAN SCATTERING

摘要

FIELD: physics.;SUBSTANCE: invention relates to pulsed solid-state lasers with radiation wavelength conversion on stimulated Raman scattering, which comprises a pumping lamp, a resonator having inside it a crystalline active element made of material which converts the radiation wavelength generated at the amplifying transition into stokes components, and a saturating filter-based Q-switch. The resonator has an output mirror which totally reflects radiation at the wavelength of the amplifying transition of the active element and maximally transmits radiation with wavelengths corresponding to amplifying transitions of the active element. The totally reflecting mirror used in the resonator is a BR-180 prism, the edge at the vertex of the dihedral angle of which is coaxial to the active element. A plane-parallel plate is placed between the active element and the prism at an angle of 45° to the optical axis of the resonator, the working surface of said plate being coated with an optical coating which minimally reflects radiation at the wavelength of the amplifying transition.;EFFECT: easy manufacture of the laser and ensuring stability of radiation energy in a wavelength range safe for the eyes in a wide range of temperature and mechanical action.;3 cl, 1 dwg
