Visible lasers are sought for in a variety of applications. They are required in fields as
diverse as medicine, materials processing, display and entertainment technology and many …

Laguerre–Gaussian (LG) beams are typical vortex beams with orbital angular momentum
(OAM), spiral wavefront phase, and donut-shaped intensity distribution. They are widely …

Abstract Trivalent praseodymium (Pr 3+) doped materials have received widely attentions
due to their promising prospects for InGaN laser-diodes pumped visible lasers. In this work …

Optical vortices are optical fields that possess a helical phase and orbital angular
momentum, which have found the application in micromanipulation, optical communication …

We report on the recent progress on continuous-wave (CW) and passviely Q-switched Pr,
Mg: SrAl 12 O 19 (SRA) bulk lasers using a 24-W diode laser as pump source. Maximum …

We report on direct generation of an orthogonally polarized dual-wavelength vortex laser, for
the first time to our knowledge, by means of a diode-pumped V-shaped Pr: YLF laser …

We reported LD pumped high-power high-efficiency continue-wave (CW) orange vortex
lasers based on a lowly-doped 15-mm-long a-cut Pr 3+(0.12 at.%): YLF crystal by a concave …

Visible pulses either by Q-switching or mode locking have been attracting intense attentions
both in solid-state lasers and fiber lasers. Here, we report on the simultaneous manipulation …

In this paper, we report two different saturable absorbers based on transition metal
dichalcogenides (TMDs) and utilize them to Q-switch a Dy 3+/Tb 3+: LuLiF 4 crystal yellow …

We report on compact blue-diode-pumped Pr, Mg: SrAl 12 O 19 (SRA) lasers in continuous-
wave and passively Q-switched regimes. For continuous-wave mode, three lasers have …
