Abstract

Efficient passive mode locking of a diode-pumped Yb3+ : KY(WO4)(2) laser using a PbS quantum-dot-doped saturable absorber is described. Pulses of 2.6 ps at around 1 mu m were generated at a pulse repetition frequency of 99 MHz with an average output power of 250 mW. A saturation fluence of 15 mu J/cm(2) and a fast temporal decay of 6 ps were measured in this quantum-dot-doped glass.
