InAs/GaAs quantum-dot saturable absorber for a diode-pumped passively mode-locked Nd : YVO4 laser at 1342 nm

Abstract

We report that lnAs/GaAs quantum dots were developed to be saturable absorbers as well as output couplers in diode-pumped passively mode-locked Nd:YVO4 lasers at 1342 nm. With an incident pump power of 12.6 W, an average output power of 0.85 W with a mode-locked pulse width of 26 ps at a repetition rate of 152 MHz was obtained. (c) 2005 Optical Society of America
