We have demonstrated stable self-starting passive mode-locking in a diode-end-pumped Nd:YVO4 laser using a semiconductor saturable absorber mirror (SESAM). An In0.25Ga0.75As single quantum-well SESAM, which was grown by the metalorganic chemical-vapor deposition technique at low temperature, acts as a passive mode-locking device and an output coupler at the same time. Continuous-wave mode-locked transform-limited pulses were obtained at 1064 nm with a pulse duration of 2.1 ps and an average output power of 1.28 W at a repetition rate of 96.5 MHz.

    We present evidence that low temperature atmosphere annealing of Co/Pd magnetic multilayers reduces both the dipolar and exchange interactions, but the dipolar interaction decreases very rapidly at the lowest temperatures. We also infer cobalt oxide formation at grain boundaries. This results in...
