SOLID-STATE LASER PUMPED MODULE AND LASER OSCILLATOR

摘要

A solid-state-laser pumping module includes a plate-shaped solid state laser material 3 for providing a gain generated by absorption of pumping light 8 to laser light to amplify the laser light, a plate-shaped slab waveguide 2 having a bonding surface portion optically bonded to a laser light incidence surface of the solid state laser material 3, for causing the pumping light 8 to be incident upon the solid state laser material 3 via the bonding surface portion thereof, a pumping light reflecting coating 4 disposed on a lateral surface of the solid state laser material 3, which is perpendicular to the laser light incidence surface, for reflecting outgoing part of the pumping light 8 which exits from the solid state laser material 3, the pumping light being incident upon the solid state laser material 3 from the slab waveguide 2, toward the inside of the solid state laser material 3, a total reflection coating 5 disposed on a surface of the solid state laser material 3, which is opposite to the laser light incidence surface, for reflecting the laser light which is incident upon the solid state laser material 3 via the light incidence surface, and which propagates through the inside of the solid state laser material 3, and a heat sink 7 for removing heat which is generated by the solid state laser material 3 and is transferred thereto via the total reflection coating 5.
