1. a kind of device of single-frequency laser beam output white light, it is characterised in that:

  • Including single-frequency laser beam A, the poly- of lens group is formedFocus lens L1With lens L2, focal length is respectively f1And f2, fluorescent media Y;

    Single-frequency laser beam A is located at condenser lens L1Side,Perpendicular to condenser lens L1, lens L2It is positioned over condenser lens L1Opposite side, in lens L2It is described afterwards equipped with fluorescent media YMirror L2Equipped with the eyeglass P for being coated with the anti-reflection of one-wavelength laser wave band, fluorescence bands high-reflecting film between fluorescent media Y1, in fluorescent media YRear is equipped with the eyeglass P of plating one-wavelength laser wave band and fluorescence bands part reflective film2Or the preceding table of the fluorescent media YFace plating one-wavelength laser wave band anti-reflection, fluorescence bands high-reflecting film S1, rear surface plating one-wavelength laser wave band and fluorescence bands part are reflectedFilm S2, the fluorescent media Y is is arranged on lens L2Fluorescent crystal, fluorescent glass or fluorescence ceramics afterwards, fluorescent media Y light transmissionsFront-back is parallel, and thickness is determined according to the expected colour temperature for obtaining light source, the equal polishing treatment of fluorescent media Y front and rear surfaces.
