Based on a lowly-doped (0.12 at.%) Pr3+: YLF crystal, high-power continuous-wave (CW)
lasers at 639 nm were obtained by laser-diode (LD) pumping. A maximum output power of …

Here we developed a novel wavelength-switchable visible continuous-wave (CW) Pr3+: YLF
laser around 670 nm. In single-wavelength laser operations, the maximum output powers of …

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 …

We present the development and characterization of high-power single-longitudinal-mode
(SLM) Pr: YLF lasers across the visible spectrum using a ring cavity design integrated with …

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 reported an InGaN laser diode pumped high-power continue-wave infrared laser based
on a Pr 3+: LiYF 4 (Pr: YLF). As pumped power was about 11.5 W at 444 nm, the maximum …

We demonstrate the direct generation of visible vortex beams (LG_01 mode) from a
doughnut-shaped diode-pumped Pr: YLF laser. In continuous-wave mode, the maximum …

In this paper, we reported and demonstrated a blue LD-pumped Pr 3+: YLF laser for the
controlled generation of orbital angular momentum (OAM) switchable vortex beams at 639 …

High-power red lasers (mainly at 639 and 670? nm) based on Pr^ 3+: YLF crystals have
been presented in many works. However, the spectral resources of Pr^ 3+: YLF in the red …

Pr 3+: YLF crystal has been demonstrated as a successful laser gain medium in the visible
region. However, the 604-nm laser based on this crystal is limited in power due to the …
