Patent ID: 8774241

Claim:
An optical module comprising: a board; a mount that is cantilevered from the board; a solid-state laser device for oscillating fundamental laser light; a pump light source that pumps the solid-state laser device; and a wavelength converting device that converts a wavelength of the fundamental laser light oscillated by the solid-state laser device, wherein the solid-state laser device, the pump light source and the wavelength converting device are each mounted on the mount, the mount being divided into three blocks, a first block on which a laser medium of the solid-state laser device is mounted, the first block having two side surfaces perpendicular to an optical axis of the laser medium, a second block on which the pump light source is mounted, the second block having two side surfaces perpendicular to an optical axis of the pump light source and a third block on which the wavelength converting device is mounted, the third block having two side surfaces perpendicular to an optical axis of the wavelength converting device, and wherein either one of a side surface and a bottom surface of only the second block is fixed to the board, the first block is fixed to the other side surface of the second block, and the third block is fixed to a side surface of the first block, wherein the optical axes coincide with each other and when the optical module is to be assembled, each of the first block and the third block is freely displaceable in any of an X axis direction, a Y axis direction and a Z axis direction outside the second block.
