Abstract
Cr4+ : YAG crystal was used as a saturable absorber in an active-passive mo de-locked Nd: YAG laser. The stable and complete mode-locked pulse train wa s achieved at 1064 nm. The duration of a single pulse was obtained from 0.8 to 2.4 ns by changing the Cr4+ :YAG crystal with different initial transmi ssion, when there was the shortest pulse width. The mode-locking dynamic pr ocess of Cr4+ : YAG crystal was analyzed by the rate equations to explain t he experimental result, and the effect of excited-state absorption was cons idered.
