The Nickel-vanadium (NiV)-layered double hydroxide (LDH) was fabricated into a novel saturable absorber (SA) by the liquid phase exfoliation method and was utilized as the laser modulator for the first time. We investigated a passive Q-switched (PQS) Tm:YAG ceramic laser at 2 μm with the NiV-LDH SA. Under an absorbed pump power of 7.2 W, the shortest pulse width of 398 ns was obtained with an average output power of 263 mW and a pulse repetition frequency (PRF) of 101.8 kHz, corresponding to a single pulse energy to be 2.30 μJ. The results indicate that the NiV-LDH SA has great research potential in the field of laser modulation.

We report a continuous-wave operation of Tm:YAG and Tm:LuAG lasers pumped with a low-cost, multimode AlGaAs laser diode. First, the lifetime and the absorbance behavior of 5 mm, 6% Tm 3+-doped YAG and LuAG crystals were thoroughly investigated. A low-cost multimode 3W laser diode at 781 nm was then used as a pump source for the Tm 3+-doped laser systems. Using three different output couplers, up to 636 mW of output power was obtained from Tm:YAG laser, with a slope efficiency of 29% at 2017 nm. The maximum output power was 637 mW in the Tm:LuAG laser, with a slope efficiency of 28% at 2023 nm. The lasing performances showed a decreasing slope efficiency with an

We report on high power and narrow linewidth laser operation of home-developed high optical quality Tm:YAG ceramic. The Tm 3+ ion is pumped directly to the upper energy level of the ∼ 2 µm laser transition ( 3 F 4 → 3 H 6 ) using a high power 1620 nm fiber Raman laser. The laser generated 15.1 W of output at 2013 nm in free running for 27.4 W of absorbed pump power, corresponding to a slope efficiency of 64.0% with respect to absorbed pump power. Employing a reflecting volume Bragg grating (VBG) as a resonator mirror and for spectrum control, the laser generated 11.8 W of 0.1 nm narrow linewidth output at 2015 nm for ∼24 W of absorbed pump power, corresponding to a slope efficiency of 61.5%.
