Abstract :
Lasing in the ultraviolet has been observed in neodymium-doped fluorozirconate glass (ZBLAN) fibres at room temperature. For a cavity output coupling of <0.1%, 74 μW of power was obtained at 381 nm ( 4Dγ2→4I11/2 transition of Nd3+) when a 45 cm long fibre was pumped with 275 mW at a wavelength of nominally 590 nm
