Abstract

A molybdenum disulfide (MoS₂) saturable absorber was fabricated by thermally decomposing the ammonium thiomolybdate. By using the MoS₂ absorber, a compact diode-pumped passively Q-switched Tm:GdVO₄ laser has been demonstrated. A stable Q-switched laser with repetition rates from 25.58 to 48.09 kHz was achieved. Maximum average output power was 100 mW with the shortest pulse duration of 0.8 μs. Maximum pulse energy is 2.08 μJ at center of 1902 nm.
