High efficiency diode-pumped femtosecond-laser-written waveguide lasers based on Pr:LiLuF4
Abstract
We present high-efficiency, diode-pumped waveguide lasers fabricated in Pr:LiLuF4 by direct femtosecondlaser writing. We demonstrated bulk-level slope efficiencies at 604 nm and 721 nm, diode-pumped lasing at 523 nm, and TEM00 laser operation at 721 nm.
