We report on single-longitudinal-mode and tunable operation of an Er:Y2O3 ceramic laser at ∼2.7 μm using intracavity Fabry-Perot etalons combined with a birefringent filter. The laser is pumped with a high brightness, narrow linewidth diode source

We report on the direct generation of the high-power optical vortices at ∼2.7 μm from an Er:Y2O3 ceramic laser end-pumped by an annular pump beam using a simple capillary fiber-based pump beam conditioning scheme. Taking advantage of the thermal g

We report on high power and narrow linewidth laser operation of home-developed high optical quality Tm:YAG ceramic. The Tm3+ ion is pumped directly to the upper energy level of the ∼ 2 μm laser transition (3F4 → 3H6) using a high power 1620 nm f

We report on high power, single-frequency operation of a compact Tm:Y2O3 ceramic laser in 2 μm spectral region employing a volume Bragg grating in a simple linear resonator to serve simultaneously as a resonator mirror and mode selector. The home de

Recent research on nonlinear multimode interference (NL-MMI) based mode-locking method provides a new approach for ultrafast all-fiber lasers. Here, we report on the polarization dynamics of group velocity locked vector solitons (GVLVSs) and noise-li

We experimentally report the novel evolutions of dissipative-soliton-resonance (DSR) pulses with respect to the pump power in an all-normal-dispersion fiber laser based on a nonlinear optical loop mirror. By solely increasing the pump power, pulse br

Abstract Physics phenomena of multi-soliton complexes have enriched the life of dissipative solitons in fiber lasers. By developing a birefringence-enhanced fiber laser, we report the first experimental observation of group-velocity-locked vector sol

An acousto-optic Q-switched self-Raman laser emitting around 1.2-1.3 μm based on cascaded conversion with the Raman shifts of 259 and 890 cm-1 was demonstrated in a c-cut Nd:YVO4 crystal. The laser starts with single Stokes emission at 1215 nm. As t
