摘要:
The present invention provides a solid state laser gain medium 28 comprising: (a) a gain layer 30 having pump regions 32 and first and second contact regions 34 and 36, respectively; (b) a first transparent layer 38 optically connected to the first contact region 34 of the gain layer 30 by diffusion bonding; and (c) a second transparent layer 40 optically connected to the second contact region 36 of the gain layer 30 by diffusion bonding. The transparent layers 38 and 40 are transparent to the lasing wavelength of the gain medium 28. The present invention also provides an apparatus for amplifying laser light, comprising: (a) a solid state, slab geometry gain medium 44 having lateral pump faces 46 and a principal radiation absorption axis C; and (b) an excitation mechanism 48 located along the pump faces 46 of the gain medium 44 for generating polarized light along a polarization axis 52 wherein the polarization axis 52 is parallel with the principal absorption axis C of the gain medium 44 to provide increased radiation absorption. The present invention also provides a cooling system 58 for a solid state gain medium 60 generating laser output laser emission at a wavelength from about 2 .mu.m to about 3 .mu.m. The cooling system 58 including a coolant material such as D2O for reducing absorption of laser emissions by the coolant at wavelengths from about 2 .mu.m to about 3 .mu.m.
