Compared with the commonly used Nd:YAG crsytal , Yb:YAG crystal has a much larger absorption bandwidth to reduce thermal management requirements for diode lasers, a longer upper-laser level lifetime, three to four times lower thermal loading per unit pump power. Yb:YAG crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
 Very low fractional heating, less than 11%.
Very high slope efficiency.
Broad absorption bands, about mailto:8nm@940nm.
No excited-state absorption or up-conversion.
Conveniently pumped by reliable InGaAs diodes.
at 940nm(or 970nm) High thermal conductivity.
High optical quality. |
