Title:
PLANAR WAVEGUIDE LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/027731
Kind Code:
A1
Abstract:
Disclosed is a planar waveguide laser device comprised of a solid-state laser module (100) and an excitation light source (1). The solid-state laser module (100) is comprised of a pair of main surfaces (31, 32) which are opposed in a predetermined direction, a pair of side surfaces (33, 34) provided on both sides of each main surface, a pair of end surfaces (35, 36) which are opposed at both ends in the predetermined direction, a laser medium (3) in which one side surface (33) is inclined at a predetermined taper angle with respect the other side surface (34) extending in the predetermined direction, an antireflection film (7) which is provided on the largely-spaced side of the side surfaces and which allows laser light to pass therethrough, and a total reflection film (6) provided on the portions of the side surfaces, which are not provided with the antireflection film. In the solid-state laser module (100), the laser light introduced into the laser medium through the portion of the side surfaces, which is provided with the antireflection film is transmitted within the laser medium while being reflected repeatedly by the side surfaces, and is returned by the narrowly-spaced side within the laser medium and, then, is transmitted to the antireflection film on the largely-spaced side, and is output through the antireflection film. The excitation light source (1) irradiates the laser medium with excitation light to excite the laser medium.
