摘要
A highly efficient milli-joule-level Q-switched Tm,La:CaF_(2)laser is experimentally demonstrated.By employing an acousto-optic modulator,the diode-pumped pulsed lasers are stably operated at repetition rates ranging from 500 Hz to 10 kHz.Dual-wavelength operation of 1881.7 nm and 1888.5 nm is achieved with slope efficiency of 64.7%.Up to 1.89 mJ of pulse energy is obtained at a pulse width of 100 ns,corresponding to a peak power of 18.88 kW.These results verified that the Tm,La:CaF_(2)crystal could be a promising candidate for achieving highly efficient and high-energy pulsed lasers.
