Passively Q-switched Tm:YLF laser
Stable passive Q-switching of a Tm: LiYF4 laser is obtained using polycrystalline Cr2+: ZnS as a saturable absorber. The achieved maximum pulse energy of 0.9 mJ and peak power of 65 kW for a pulse duration of ∼14 ns represent substantial improvement and highest values for a passively Q-switched diode-pumped Tm laser operating at ∼1.9 μm.

Heterostructure ReS2/GaAs Saturable Absorber Passively Q-Switched Nd:YVO4 Laser
Heterostructure ReS2/GaAs was fabricated on a 110-μm (111) GaAs wafer by chemical vapor deposition method. Passively Q-switched Nd:YVO4 laser was demonstrated by employing heterostructure ReS2/GaAs as a saturable absorber (SA).

A random Q-switched fiber laser [PDF]
Abstract Extensive studies have been performed on random lasers in which multiple-scattering feedback is used to generate coherent emission. Q-switching and mode-locking are well-known routes for achieving high peak power output in conventional lasers.
