  • Second harmonic generating method and apparatus thereof
    Patent number: 5384796
    Abstract: A method and apparatus for second harmonic generation of laser light includes a non-linear birefringent crystalline element and a dynamic laser rod which has two transmission faces and an optical axis, the face of the dynamic laser rod facing the non-linear birefringent crystalline element being inclined at an angle to the optical axis of the dynamic laser rod so that the optical axis of the birefringent crystalline element forms a Brewster angle with a normal to the inclined face of the dynamic laser rod. Thus, the internal space occupied by the second harmonic generating apparatus is reduced and the supporting structure is miniaturized.
