摘要： A solid-state laser device includes an inner container, an outer container, a cooling medium supply unit, and a cover section. The inner container in which a laser medium is accommodated includes an inner light-transmitting unit. An outer light-transmitting unit of the outer container is provided at a part that faces the inner light-transmitting unit and is vacuum-insulated from the inner light-transmitting unit. The cooling medium supply unit supplies a cooling medium so that the cooling medium comes in contact with a surface other than a light input and output surface in the laser medium. The cover section partitions a light-passing area from a cooling medium supply area to which the cooling medium is supplied.

摘要： A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials. A lamp driven slab design with a face-to-face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface is utilized. A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.
