摘要
PROBLEM TO BE SOLVED: To provide a laser beam irradiation device allowing easy alignment.;SOLUTION: A laser light irradiation device 1 includes an optical waveguide 10, laser light sources 201 to 20N, lenses 211 to 21N, an optical fiber array 30, and a lens 40. The optical waveguide 10 guides light made incident on an incident end 11 to emit the light from an emission end 12 and includes a core 13 extending in a Z direction from the incident end 11 toward the emission end 12 and a clad 14 surrounding the core 13. In a cross section vertical to the Z direction of the optical waveguide 10, a width of the core 13 in a Y direction out of X and Y directions orthogonal to each other is greater than that in the X direction. The optical waveguide 10 is provided with a clad mode light removal part 14a for removing clad mode light, on an outer peripheral surface of the clad 14.;COPYRIGHT: (C)2012,JPO&INPIT
