Fiber laser emits in the UV and at 412 nm

Roomtemperature operation of a fiber laser emitting in the UV has been demonstrated for what is believed to be the first time by researchers at the University of Illinois at UrbanaChampaign (Urbana, IL). Using a 45cmlong neodymiumdoped fluorozirconate (Nd:ZBLAN) glass fiber pumped with 275 mW from a CW scanning ring dye laser around 590 nm, David Funk and Joe Carlson obtained 75 µW at 381 nm from the upconversion laser. The output coupling was only 0.1%, and Funk and Carlson expect the outpu

The output coupling was only 0.1%, and Funk and Carlson expect the output will increase to several milliwatts with higher output coupling.
