Abstract
Thulium- (Tm-)doped fluorozirconate (ZBLAN) fiber can be pumped by infrared (IR) light that is resonant with the 4f electronic energy levels. With the long lifetimes of these levels, upconversion processes are possible. Accompanied by the appropriate IR wavelengths and optical feedback, upconversion can result in lasing near 480 nm with powers over 100 mW. We discuss the parameters of our laser experiment and the expected results.
