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 …

A mechanism of assembling the multi-metastable levels as a composite-metastable level
was proposed, enabling wide tuned emission as large as a few ten nanometers, and …

As deep-red semiconductor lasers are still in development, high-power deep-red lasers
have traditionally relied on excimer or dye lasers, or nonlinear frequency conversion of near …

Visible lasers based on blue laser diodes (LDs) pumped trivalent rare-earth ions doped
crystal have recently attracted growing attention due to their advantages of high-efficiency …

We report on diode-pumped continuous-wave Pr-doped yttrium lithium fluoride (Pr: YLF)
laser and its frequency doubling to 320 nm. The maximum output power of the 640 nm …

We report on a high-repetition-rate and high-beam-quality all-solid-state nanosecond pulsed
deep-red laser source by intracavity second harmonic generation of the actively Q-switched …

We report on a double-clad fiber laser operating on the^ 3P_0→^ 3F_4 Pr^ 3+ transition (in
the deep-red spectral range) pumped by a GaN diode laser at∼ 442 nm. It employs a 0.8 …

We reported a continuous-wave (CW) deep red laser at 718.5 nm in a Pr 3+: YLF crystal
pumped by an InGaN laser diode. A maximum output power of 3.95 W with an average …

This paper reports the single-longitudinal-mode (SLM) laser output of Pr: YLF at 721.2 nm by
inserting double Fabry–Perot (F–P) etalons into the cavity. We use the correlation rate …

We demonstrated 22 W LD-pumped high-power continuous-wave (CW) deep red laser
operations at 718.5 and 720.8 nm based on an a-cut Pr 3+: YLF crystal. The output power of …
