摘要：

We report, for the first time to our knowledge, an acousto-optic Q-switched Er,Yb:YAl3(BO3)(4) crystal laser operating in the 1.5-1.6 mu m spectral region. The output characteristics of the lasers with different duty cycles, pulse repetition frequencies (PRF) and output couplers were investigated. The maximum single pulse energy of 91 mu J with the pulse width of 135 ns and the PRF of 5 kHz was achieved when the transmission of output coupler T = 1% and the duty cycle was optimized at 2.5%. The shortest pulse width of 90 ns was obtained at the PRF of 3 kHz for the transmission of output coupler T = 1.5%. The blue shift of laser emission and shortening of pulse width with reduction of PRF and increment of the pump power were observed.
