Abstract

Saturable absorber Q switching of the cw diode-pumped Nd 3+:KGd(WO 4)2 and Nd 3+:YVO 4 lasers at 1.3 μm with PbS Quantum Dots (QDs) doped phosphate glass is demonstrated and compared. Q-switched pulses of minimum 110 ns in duration and maximum average output power of 14 mW were obtained. The bleaching decay time of the PbS-doped samples was measured and found to decrease with QDs size decreasing due to enhancement of the quantum confinement effect for smaller QDs.
