We report on our latest experimental results concerning laser oscillations at low-gain lines of diode-pumped Nd:YAG crystal lasers on 4F3/2 → 4I13/2 transition and MoS2 -based dual-wavelength passively Q-switched Nd:YAG laser on this transition, for the first time to our knowledge. Using an undoped YAG as etalon to promote the intracavity loss modulation, three new lasing lines of about 1333, 1334, and 1340 nm have been achieved. Especially, the 1334-nm laser can be operated at single wavelength mode with maximum output power of 2.03 W. Dual-wavelength passively Q-switched Nd:YAG laser at 1318 and 1338 nm has also been obtained with maximum average output power of 0.44 W. The shortest pulse width is about 150 ns at pulse repetition rate of 125 kHz, leading to single pulse energy of 3.5 μJ and pulse peak power of 23.4 W.
