Abstract： |
The invention includes discharge tube of helium-neon laser and two cavity mirrors setup at two ends of the discharge tube. Technical features are that cats eye reversal unit is adopted for one or to cavity mirrors. The cats eye reversal unit is composed of one convex lens or composed of lens group and a concave mirror. Vertex of convex lens is placed within focal length of lens group or at focus. The invention overcomes disadvantages of difficult to be adjusted and to ensure stability, and large temperature drift. Transverse modes of output laser light can be selected in order to output base transverse mode. Under large gain, free of adjustment is possible. The invention also discloses dedicated device for testing cats eye reversal unit. |
