Abstract.

A high-resolution spectroscopic and emission-decay investigation of highly concentrated Nd:YAG single crystals and ceramics shows that the state of the Nd3+ ions and their interaction in these materials are similar and can be used for construction of efficient solid-state lasers directly pumped in the emitting level. This possibility is demonstrated by continuous-wave emission of concentrated Nd:YAG crystals with up to 3.5 at. % Nd and ceramics with up to 6.8 at. % Nd under resonant 885-nm end pump.
