Introduction |
 |
 |
Yb:YAG is one of the most promising laser-active materials and more suitable for diode-pumping than the traditional Nd-doped systems. diode lasers a longer upper-laser level lifetime three to four times lower thermal loading per unit pump power. Yb:YAG crystal at 1030nm is a good substitute for a Nd:YAG crystal at 1064nm and its second harmonic at 515nm may replace Arion laser(with a large volume) which emit at 514nm. |
