An Nd:YVO4 laser which was passively modelocked at the very high repetition
rate of similar to 77GHz, using a semiconductor saturable absorber mirror
(SESAM), is demonstrated. The soliton-like pulses are well separated in tim
e and their duration is 2.7ps. The required negative dispersion is introduc
ed by a GTI-like structure, which is formed by the gain medium and the SESA
M.
