Laser emission under resonant pump in the emitting level of concentrated Nd:YAG ceramics

The possibility of using the thermally activated optical absorption bands for a resonant pump in the emitting level of highly doped Nd laser materials is discussed. This potential is demonstrated by the continuous wave 1064 nm laser emission under 885 nm pump in concentrated (up to 6.8 at. %) Nd:YAG ceramics. (C) 2001 American Institute of Physics.
