| Abstract: | Laser performance of 1064nm domestic Nd:YAG ceramic lasers for 885nm direct pumping and 808nm traditional pumping are compared. Higher slope efficiency of 34% and maximum output power of 16.5W are obtained for the 885nm pump with a 6mm length 1at.% Nd:YAG ceramic. The advantages for 885nm direct pumping are discussed in detail. This pumping scheme for highly doping a Nd:YAG ceramic laser is considered as an available way to generate high power and good beam quality simultaneously. |
