A Diode-Pumped Dual-Wavelength Tm, Ho: YAG Ceramic Laser
A diode-pumped dual-wavelength CW Tm, Ho: YAG ceramic laser was demonstrated for the first time to our knowledge. A maximum output power of ∼1.2 W with a beam quality factor ${\rm{M}}^{2}\,= \,1.19$ has been generated from the 3at.% Tm, 0 ...

All-Fiber Gas Raman Laser by D2-Filled Hollow-Core Photonic Crystal Fibers
We report here an all-fiber structure tunable gas Raman laser based on deuterium-filled hollow-core photonic crystal fibers (HC-PCFs). An all-fiber gas cavity is fabricated by fusion splicing a 49 m high-pressure deuterium-filled HC-PCF with two solid ...

High average power 1314 nm Nd:YLF laser, passively Q-switched with V:YAG [PDF]
A 1314 nm Nd:YLF laser was designed and operated both CW and passively Q-switched. Maximum CW output of 10.4 W resulted from 45.2 W of incident pump power. Passive Q-switching was obtained by inserting a V:YAG saturable absorber in the cavity.

Dual-Wavelength Passively Mode-Locked Yb-Doped Fiber Laser Based on a SnSe2-PVA Saturable Absorber
In this letter, tin diselenide (SnSe2) was successfully prepared with the liquid-phase exfoliation method and embedded into polyvinyl alcohol as a saturable absorber (SA) in a dual-wavelength passively mode-locked Yb-doped fiber laser. Stable mode-locked

Alexandrite lasers with blue-diode-pumping
The availability of high-power and high-brightness blue diode lasers makes them attractive as low-cost pump sources for broadly tunable Alexandrite lasers. In this paper we investigate the performance of an Alexandrite laser pumped by a high-power fiber-delivered blue diode module.

InGaN-LD-Pumped
We demonstrate the first InGaN-LD-pumped room temperature and continuous-wave laser operation of a Pr3+: LiYF4 crystal at 915 nm. A maximum output power up to 78 mW with a laser slope efficiency of about 17% is obtained. The round-trip optical losses are

Electrically driven lasing in metal halide perovskites: Challenges and outlook
Metal halide perovskite semiconductors have shown great potential as emissive layers in light-emitting diodes and gain media in optically pumped lasers, and thus represent a possible foundation for a non-epitaxial electrically driven laser diode. However,

Generation of a 578-nm Yellow Laser by the Use of Sum-Frequency Mixing in a Branched Cavity
A compact, continuous-wave, solid-state laser at 578 nm has been demonstrated, for the first time to our knowledge, by use of intracavity sum-frequency mixing from a branched cavity with an LBO crystal. Two gain mediums, namely, the Nd:YAG single crystal
