SLAB LASER AND AMPLIFIER AND METHOD OF USE

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.

主权项

1. A system for transferring a material from a first object to a second object, comprising:
a laser device comprising:
a slab crystal comprising a front side, a back side, a top side, a bottom side, a left side, and a right side, wherein said back side is at least partially mirrored and wherein said slab crystal is configured to receive a seed laser beam into the front side, and also configured to emit an amplified laser beam from said front side, anda pumping light source providing light energy to the slab crystal to amplify said seed laser beam in said slab crystal; and a laser routing subsystem configured to direct the amplified laser beam to vaporize a portion of the first product to deposit a part of the vaporized portion on or in the second object.
