CW Room temperature upconversion lasing at blue, green and red wavelengths in infrared-pumped Pr<sup>3+</sup>-doped fluoride fibre
Continuous-wave, room temperature laser oscillation at 491 nm, 520 nm, 605 nm and 635 nm in a Pr<sup>3+</sup>-doped fluoro-zirconate fibre pumped simultaneously at 1.01 µm and 0.835µm is reported. An output power of 185mW has been measured for the 635 nm transition. The thresholds obtain...
