Abstract
A diode-laser side-pumped solid-state laser device (SSLD) has a cylindrical laser rod, a cooling tube, and a cylindrical mirror member having an inner mirror surface and a plurality of openings therein for introducing pumping laser. The laser rod receives the pumping laser, absorbs a portion of the pumping laser, and passes and focus the remaining portion of the pumping laser at a focal point disposed on the mirror surface. Substantially all the remaining portion of the pumping laser is reflected to be received and absorbed by the laser rod.
Claims20
A diode-pumped solid-state laser device (SSLD) comprising a cylindrical laser rod for absorbing pumping laser to generate solid-state laser, a cooling member disposed radially outside and co-axially with said laser rod, and a mirror member having a substantially cylindrical inner surface disposed radially outside and co-axially with said cylindrical laser rod, said mirror member having an opening for receiving therethrough pumping laser and a mirror surface for reflecting a portion of the pumping laser passed by said laser rod, said laser rod receiving said pumping laser through said opening and focusing the portion of said pumping laser at a focal point substantially on said mirror surface.
