摘要：

This paper reports on efficient generation of cw laser radiation at 0.9 and 1.3 mu m in different neodymium doped laser hosts. The thermal, mechanical and optical properties as well as the laser performance of Nd:YAG, Nd:YAlO3, Nd:YVO4 and Nd:GdVO4 are studied in numerical simulations as well as in experimental investigations. For example an output power of more than 4.0W is generated in Nd:YVO4 at the 914 nm F-4(3/2)-> I-4(9/2) transition using a pump power of 19 W. In Nd:GdVO4 more than 6.0W are obtained at the 1342 nm F-4(3/2)-> I-4(13/2) laser transition by using a pump power of 19.3W. The spatial beam quality of both lasers is diffraction limited with an M-2 value of less than 1.1.
