Abstract
We demonstrate the first use of InGaAsP quantum wells as a saturable absorber in the Q-switching of a diode-pumped Nd-doped 1.3μm laser. The barrier layers of the InGaAsP quantum-well device are designed to be a strong absorber for the suppression of the transition channel at 1.06μm. With an incident pump power of 1.8W, an average output power of 160mW with a Q-switched pulse width of 19ns at a pulse repetition rate of 38kHz was obtained.
