Abstract

Saturable absorber Q-switching of the 1.5 μm Er:glass laser has been obtained using slowly-relaxing divalent uranium ions in Ca, Sr, and Ba:F2, and fast-relaxing divalent cobalt ions in Y3Sc2Ga3O12 (YSGG) and Y3Al5O12 (YAG). Pulsewidths as short as 20 nanoseconds have been demonstrated without optical damage in both cases. Spectroscopic measurements, as well as Q-switched laser results are discussed for all of these materials.
