Passively Q-Switched Er:LuAG Laser at 1.65 μm Using MoS2 and WS2 Saturable Absorbers

IEEE Photonics Journal, 2017
We describe passively Q-switched Er:LuAG laser characteristics at 1.65 μm for the first time, with MoS2 and WS2 as the saturable absorber, respectively. The saturable absorbers were both prepared with the liquid phase exfoliation method.

Slow light in saturable absorbers [PDF]

Physical Review A, 2008
In connection with the experiments recently achieved on doped crystals, biological samples, doped optical fibers and semiconductor heterostructures, we revisit the theory of the propagation of a pulse-modulated light in a saturable absorber. Explicit analytical expressions of the transmitted pulse are obtained, enabling us to determine the parameters ...
