Sum-frequency generation between an actively synchronized ultrashort Ti : sapphire laser and a Nd : YVO4 laser

摘要

We realized stable synchronization between a femtosecond Ti:sapphire laser and a picosecond Nd:YVO4 laser by using a precise phase-locked loop technology; ultrashort laser pulses at a wavelength around 460 nm were generated by frequency mixing both laser branches. This work demonstrated a feasible way to extend the available ultrashort laser wavelength through nonlinear frequency mixing technology. (C) 2008 Optical Society of America.
