摘　　要：A diode-pumped passively Q-switched Nd：YLF laser was demonstrated by using saturable absorber of Cr^4＋：YAG. At the incident power of 7.74 W, pure passively Q-switched laser with per pulse energy of 210 μJ and pulse width of 19.6 ns at repetition rate of 1.78 kHz was obtained by using Cr^4＋：YAG with initial transmission of 80%. At the incident power of 8.70 W, a Q-switched mode-locking with average output power of 650 mW was achieved, the overall slop efficiency was 16%, corresponding to the initial transmission of 85% of Cr^4＋ ：YAG.A diode-pumped passively Q-switched Nd：YLF laser was demonstrated by using saturable absorber of Cr^4＋：YAG.
