Visible laser emission from a praseodymium-doped fluorozirconate guided-wave chip

We report visible continuous-wave laser emission at 636 nm from a praseodymium-doped fluorozirconate glass guided-wave chip laser. This ultra-fast laser inscribed gain chip is demonstrated to be a compact and integrated laser module. The laser module, pumped by 442 nm GaN laser diodes, generates > 8 mW lasing output with a beam quality of M-xy(2) similar to 1.15 x 1.1(+/- 0.1). To the best of our knowledge, this is the first visible laser emission from a glass-based wave-guide chip laser. (C) 2017 Optical Society of America
