Abstract
Pumped with two 970nm, InGaAs strained-layer diode arrays, a side-pumped Er,Yb:phospha te glass laser has been const ructed. The long pulse slope eff iciency was 14%, and threshold occurred wit h 60mJ input. The maximum output pulse energy was 20.5mJ, wit h output wavelengt hs at 1545 ± 12nm. When Q-switched, the laser prod uced 0.3mJ, 46ns FWHM pulses at an output wa velengt h of 1533 ± 1nm and wit h a repetition rate of 7Hz.Keywords
