Abstract
A single-layer graphene saturable absorber is employed for passive -switching of an Er, (Er,Yb:GdAB) compact laser, representing the first Er-doped oxoborate laser -switched by graphene. This laser is based on a -cut 1.8 at. % , 15 at. % crystal diode-pumped at 0.976 μm. It generates a maximum average output power of 360 mW at 1.55 μm with a slope efficiency of 23% (with respect to the incident power). Stable pulses are achieved at a repetition rate of 400 kHz. This result represents, to the best of our knowledge, the shortest pulse duration ever achieved in bulk Er lasers -switched by 2D materials. Graphene is a promising material for generating nanosecond pulses at high repetition rates (MHz range) in Er-doped oxoborate lasers emitting in the eye-safe range at 1.5–1.7 μm.
