High repetition rate microchip Er3+,Yb3+:YAl3(BO3)4 diode-pumped laser
Diode-pumped passively Q-switched microchip Er,Yb:YAl3(BO3)4 laser for range-finding has been demonstrated. By using a Co2+:MgAl2O4 as a saturable absorber TEM00-mode Q-switched average output power of 315 mW was demonstrated at 1522 nm with pulse duration of 5 ns and pulse energy of 5,25 μJ at a repetition rate of 60 kHz.
