Generation of High Peak Power Mode-Locked Green Pulses Based on WS(2) and EOM: Experiment and Theory

Based on an as-prepared high-quality WS(2) film and an electro-optic modulator (EOM), a dual-loss-modulated low repetition rate mode-locking laser at 0.53 μm with high peak power is presented for the first time. The laser characteristics versus the pump power are investigated experimentally and theo...

description Based on an as-prepared high-quality WS(2) film and an electro-optic modulator (EOM), a dual-loss-modulated low repetition rate mode-locking laser at 0.53 μm with high peak power is presented for the first time. The laser characteristics versus the pump power are investigated experimentally and theoretically. At a pump power of 10.67 W, the shortest pulse duration of 305 ps can be measured, corresponding to the highest peak power of 931 kW, which is much higher than those of the single passive modulated lasers with WS(2)-SA. A simple rate equation simulation was used to describe this dual-loss-modulated mode-locking green laser based on WS(2) and EOM. The results of the numerical simulation are basically in accordance with the experimental values.
