摘要:By simultaneously employing electro-optic (EO) modulator and multiwalled carbon nanotube (MWCNT) in a doubly Q-switched mode-locked (QML) Nd:Lu0.5Y0.5VO4/KTP laser, a low repetition rate subnanosecond Nd:Lu0.5Y0.5VO4/KTP green laser with high peak power is presented. Since the repetition rate of this pulsed green laser is controlled by the EO modulator, highly stable laser pulses with low repetition rates of 1-5 kHz are obtained. As the pulse duration of this laser depends on the mode-locked pulse width underneath the Q-switched envelope, subnanosecond green laser pulses with high peak power can be generated. The average output powers, pulse widths as well as peak powers versus incident pump power under different repetition rates are measured. The shortest pulse duration of 415 ps and the highest pulse energy of 424 mu J are obtained at the repetition rate of 1 kHz, corresponding to a peak power of as high as 1022 kW. The experimental results show that the dual-loss modulation technology with EO and MWCNT in QML laser is an efficient method in generating low repetition rate subnanosecond pulse green laser.
