Article Description

The first, to the best of our knowledge, mid-infrared Q-switched Ce-doped glass laser is demonstrated. As saturable absorbers, Fe:CdSe and Fe:CdTe are used for the first time. When Q-switched by Fe:CdSe, the laser operates in a multi-pulse regime with an individual pulse width of 110 ns, centered at λ = 5.20 µm. With Fe:CdTe as saturable absorber, 1–3 giant pulses of 30 ns pulse width are generated at λ = 5.13 µm.
