Y. Nagasawa et al., Generation of 30 fs pulses at 635 nm by frequency doubling of cavity-dumped chromium-doped forsterite laser, and its application to spectroscopy, APP PHYS B, 70, 2000, pp. S33-S36
A cavity-dumped Kerr-lens mode-locked chromium-doped forsterite (Cr:F) lase
r was developed. The fundamental frequency of 1270 nm was converted into 63
5 nm by second-harmonic generation in an LBO crystal. A pulse duration of 3
0 fs was obtained at 635 nm with energy of 3.8 nJ. The developed laser was
applied to single-wavelength pump-probe measurements of dyes, malachite gre
en (MG) and phenol blue (PB).
