Abstract
Continuous oscillation on the 2P3/2 → 4I11/2 transition of Nd3+ in a fluorozirconate glass (ZBLAN) fiber at room temperature has been observed. When pumped at ~590 nm, a Nd:ZBLAN fiber 39 cm in length lases in the violet at 412 nm and produces ~0.5 mW of power for 320 mW of pump power and a cavity output coupling of 0.4%. The breadth of the laser’s excitation spectrum is ~12 nm (581–593 nm).
