Abstract
ontinuous-wave laser operation of bulk Er:Yb:phosphate glass pumped at 980 nm by an InGaAs index-guided diode laser has been achieved for the first time to our knowledge, with 2 mW of output power obtained at 1.54 µm. To optimize pumping conditions and to investigate the effects of pump wavelength, the Er3+:Yb3+ glass disk has also been pumped by a Ti:Al2O3 laser at 960 and 980 nm, and we obtained high output power (70 mW) and the highest slope efficiency (21% for 980-nm pumping) reported to date for a bulk Er:glass laser.
