Cho Don-Cho Dien is a potential area for lead-zinc deposits with reserves of about 40% of Vietnam’s total lead-zinc ores. Most of the deposits are hidden. The results of geological structural analysis have shown that the lead-zinc mineralization he

We report on a high-peak-power acousto-optically Q-switched Er:Y2O3 ceramic laser operating at room temperature. Stable pulses with a duration of 41-190 ns (FWHM) are generated at approximately 2.7 μm with the repetition rate varying from 0.3 to 10

Manipulation of group-velocity-locked vector solitons (GVLVSs) is numerically proposed and experimentally demonstrated. A pseudo-high-order GVLVS could be generated from a fundamental GVLVS with the help of a polarization-resolved system. Specificall

We numerically found that an intracavity nonlinear absorber (saturable absorber or reversed saturable absorber) plays a crucial role in the formation of dissipative bright or dark solitons in a fiber laser. The operation of an all-normal-dispersion f

Multilayered combination of protective structures is an important means of effectively weakening the explosive shockwave. On this basis, a “rigid-flexible-rigid” three-layer sealed structure was proposed in this paper and two models for the seale

We report on the first experimental observation of bound states of vector dissipative solitons (VDSs) in an erbium-doped fiber laser mode locked with a semiconductor saturable absorber mirror and operated in the normal dispersion regime. Bound states

Gold nanorods (GNRs) with surface plasmon resonance peak at 1063.8 nm were fabricated and experimentally exploited as the single and combined saturable absorber (SA) in a Q-switched Nd:YAG laser for the first time. In the situation using GNRs as a si
