Abstract
Disclosed is a laser device including: a rod-shaped laser medium extending in a first direction; a first light source unit including a first base having a first notch through which the laser medium passes and a plurality of excitation light sources attached to the first base; and a holder supporting the laser medium and the first light source unit. At least one of the first base and the holder includes a first regulating part configured to regulate a position of the first base with respect to the holder.
Claims11
A laser device comprising:
- a rod-shaped laser medium extending in a first direction;
- a first light source unit including a first base having a first notch through which the laser medium passes and a plurality of excitation light sources attached to the first base;
- a second light source unit arranged side by side with the first light source unit in the first direction, the second light source unit including a second base having a second notch through which the laser medium passes and a plurality of excitation light sources attached to the second base;
- and
- a holder supporting the laser medium, the first light source unit, and the second light source unit,
- wherein the first light source unit and the second light source unit are each fixed to the holder,
- wherein at least one of the first base and the holder includes a first regulating part configured to regulate a position of the first base with respect to the holder,
- wherein at least one of the second base and the holder includes a second regulating part configured to regulate a position of the second base with respect to the holder,
- wherein the holder includes a first holding member and a second holding member arranged side by side in the first direction, a connecting member connecting the first holding member and the second holding member to each other, and a partition member attached to the connecting member between the first holding member and the second holding member,
- wherein the first light source unit is disposed between the first holding member and the partition member, and the second light source unit is disposed between the second holding member and the partition member,
- wherein the partition member includes a first stopper as the first regulating part and includes a second stopper as the second regulating part,
- wherein the first stopper is configured to restrict rotation of the first base in a circumferential direction centered on a center line of the laser medium in a case where the first light source unit is not fixed to the holder, and
- wherein the second stopper is configured to restrict rotation of the second base in the circumferential direction in a case where the second light source unit is not fixed to the holder.

A method for manufacturing a laser device, comprising:
- a step of preparing a holder supporting a rod-shaped laser medium extending in a first direction, the holder including a first holding member and a second holding member arranged side by side in the first direction, a connecting member connecting the first holding member and the second holding member to each other, and a partition member attached to the connecting member between the first holding member and the second holding member and provided with a first stopper and a second stopper,
- a step of preparing a first light source unit including a first base having a first notch and a plurality of excitation light sources attached to the first base, and a second light source unit including a second base having a second notch and a plurality of excitation light sources attached to the second base;
- a step of disposing the first base on the holder from one side in a second direction intersecting with the first direction while the laser medium is passed through the first notch between the first holding member and the partition member;
- rotating the first base to one side in a circumferential direction centered on a center line of the laser medium until rotation thereof is restricted by the first stopper, and fixing the first light source unit to the holder;
- and
- a step of disposing the second base on the holder from the one side in the second direction while the laser medium is passed through the second notch between the second holding member and the partition member, and rotating the second base to the other side in the circumferential direction until rotation thereof is restricted by the second stopper, and fixing the second light source unit to the holder.
