The rise of semiconductor‐based pump sources such as InxGa1‐xN‐laser diodes or
frequency‐doubled optically pumped semiconductor lasers with emission wavelengths in …

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 …

Pure and Pr3+-doped BaYF5 nanoparticles were synthesized by the microwave
hydrothermal method. The nanoparticles were characterized by X-ray diffraction (XRD) …

We report on a red praseodymium fiber laser delivering 1.07 W at 634.5 nm with a slope
efficiency of 20.7%(versus the incident pump), a laser threshold of 0.55 W, and a single …

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 …

In recent years, great interest has been paid to Pr 3-doped materials, because they can offer
a large range of laser transitions in the blue, green, orange, red, and deep red spectral …

By partially substituting the Y 3+ ions with Lu 3+ ions, the widely investigated Pr: LiYF 4
single crystal has been formated into Pr: LiY 0.3 Lu 0.7 F 4 mixed crystal. In this work, we …

In this work, we explore emission properties of Pr 3+ ion doped aluminosilicate glasses at
visible wavelengths where alkaline earth oxide modifiers (Mg 2+, Ca 2+, Sr 2+, Ba 2+) are …

We present here the first tunable continuous-wave (CW) simultaneous dual-wavelength
laser operation of a Pr 3+: LiYF 4 crystal in the 900 nm spectral range using a single …

The spectroscopic properties of the Pr-doped CaF 2 crystals are investigated. The
photoluminescence intensity in the visible region is drastically enhanced by co-doping Gd …
