Abstract

Picosecond blue light pulse generation by frequency doubling of a gain-switched GaAlAs laser diode in a proton-exchanged MgO:LiNbO3 waveguide is reported. High-peak fundamental pulse power of 1.23 W is obtained by employing a laser diode with saturable absorbers. Blue light pulse of 7.88 mW maximum peak power and 28.7 ps pulse width is generated in the form of Cherenkov radiation.
