Abstract
High powered laser including a microchip laser array having an array of microchip laser beam shooting parts, and a heat transfer member of a material with a high thermal conductivity fitted between, and in contact with, the microchip laser beam shooting parts, for transferring heat from the microchip laser beam shooting parts to the outside of the high powered laser, thereby enhancing an output.
Claims10
A high powered laser comprising:
- a microchip laser array having an array of microchip laser beam shooting parts, each comprising a laser diode, a focusing optical system, and a resonator having a laser medium and nonlinear material;
- a heat transfer member of a material with a high thermal conductivity fitted between said laser beam shooting parts, and in contact with top, bottom and side surfaces of each of said microchip laser beam shooting parts, for transferring heat from the microchip laser beam shooting parts to the outside of the high powered laser and;
- a cooling member fitted in contact with the heat transfer member for forcible cooling of the heat transferred to the heat transfer member by water or air.
