Title:
Planar waveguide type laser device
Document Type and Number:
Japanese Patent JP5933754
Kind Code:
B2
Abstract:
A laser medium 21 is shaped like a plate and has a waveguide structure in a direction of the thickness of a surface thereof perpendicular to the optical axis thereof. A nonlinear material 31 is placed on the optical axis of the laser medium 21 close to the laser medium 21 and has a waveguide structure in the same direction as that of the waveguide structure of the laser medium 21. A 1/4 wavelength plate 41 is placed close to one of surfaces, which are perpendicular to the optical axis, of the nonlinear material 31, the one being opposite to a surface close to the laser medium 21.
