Output Characteristic of Actively-Controllable Passively Q-Switched Laser
The micro-cavity Cr4+:YAG/Nd:YAG passively Q-switched laser pumped by pulse-pump and pre-pump mechanism is investigated theoretically and experimentally. The experiments show that with large pulse width and high repetition rate of pump pulse, the dependent jitter scope of output laser pulse with pump pulse is increased. By reducing pump pulse width and repetition rate, the 1.06 μm laser with 3.8 ns pulse width and single pulse energy of 65 μJ is obtained. The dependent jitter scope of output laser pulse with pump pulse is lower than 0.8 μs. At the same time, the advantage and disadvantage of pre-pump mechanism is analyzed.
