7 March 2019 Enhancement of saturable absorption performance by modifying MoS2 with polypyrrole
Author Affiliations +
A innovative modification method based on polypyrrole (PPy) was developed as an effective way to improve the saturable absorption performance of MoS2. By employing the homemade MoS2-PPy copolymers as saturable absorber (SA), a diode-end-pumped passively Q-switched Nd:LLF laser at 1.06 μm was demonstrated. Based on a MoS2-PPy nanosheet saturable absorber, a pulsed laser output with 93 ns pulse width was achieved, which was nearly half of the pulse width using MoS2 as saturable absorber. Meanwhile, the pulse peak power reached 75 W.
