Abstract
A molybdenum disulfide (MoS2) saturable absorber (SA) solution is fabricated by liquid-phase exfoliation (LPE) method. By using the MoS2-SA solution, a compact diode-pumped passively Q-switched Ti:Sapphire laser has been demonstrated. The minimum short pulse width is 3.7 ns and the maximum pulse energy is 16.2 μJ at 1 kHz repetition rate. Our results show that MoS2-SA solution can be developed as an effective saturable absorber to achieve nanosecond pulse laser in the infrared range.
