Abstract:
In a planar waveguide laser device ( 1 ), a substrate ( 6 ) is joined to the upper surface of a waveguide ( 2 ). A recess ( 6 a ) having a chamfered shape is formed along an edge of an end facet of the substrate ( 6 ) on the side of the waveguide ( 2 ), the end facet being perpendicular to the direction of laser oscillation. An end facet of the waveguide ( 2 ) perpendicular to the oscillation direction of laser light is covered with a coating ( 7 ). A wraparound portion ( 7 a ) continuing from the coating ( 7 ) covers the upper surface of the waveguide ( 2 ) facing the recess ( 6 a ) of the substrate ( 6 ).

Claim (Index 1):
A planar waveguide laser device comprising:\n a waveguide including a laser medium having a flat plate-like shape, an upper cladding joined to an upper surface of the laser medium, and a lower cladding joined to a lower surface of the laser medium; a substrate joined to an upper surface of the waveguide; the substrate comprising a recess with a chamfered shape along an edge of an end facet of the substrate, the edge facing the waveguide, and the end facet of the substrate being perpendicular to an oscillation direction of laser light; and a coating continuously covering an end facet of the waveguide perpendicular to the oscillation direction of laser light, and an upper surface of the waveguide facing the recess of the substrate.
