摘要:

We report on frequency doubling of the 647.1 nm line from a mode‐locked Kr+laser in a single‐mode fiber with pure Ge‐doped core. The harmonic light at 323.5 nm builds up after about 20 min of laser irradiation at 647.1 nm. Peak powers as low as 600 W were sufficient to prepare the fibers for second harmonic generation.
