Title:
LASER LIGHT GENERATOR
Document Type and Number:
Japanese Patent JPH04241484
Kind Code:
A
Abstract:
PURPOSE: To generate laser light with much energy concentrated in a narrow divergence angle.
CONSTITUTION: Pumping laser light output from a plurality of laser diodes 1a to 1d is applied to different positions of a laser medium 6. Thus heat lenses 6a to 6d are formed in the laser medium 6. Four laser light beams generated from the laser medium 6 are input to a non-linear optical crystal element, 9. Second harmonics of the same phase are generated from the nonlinear optical crystal element 9.
