Simultaneous tri-wavelength laser operation at 916, 1086, and 1089 nm of diode-pumped Nd: LuVO4 crystal

摘要

We report a diode-pumped continuous-wave tri-wavelength Nd: LuVO4 laser operating at 916, 1086, and 1089 nm. A theoretical analysis has been introduced to determine the threshold conditions for simultaneous tri-wavelength laser operation. Using a T-shaped cavity, we realized efficient tri-wavelength operation at F-4(3/2) -> I-4(9/2) and F-4(3/2). I-4(11/2) transitions for Nd: LuVO4 crystal, simultaneously. The maximum output power was 2.8 W, which included 916, 1086, and 1089 nm, and the optical conversion efficiency was 15.1%. To our knowledge, this is the first work that realizes simultaneous tri-wavelength Nd: LuVO4 laser operation.
