All-optical active mode locking of a picosecond Nd:YVO4 laser is demonstrated by use of an intracavity semiconductor nonlinear Fabry--Perot mirror. The reflectivity of the Fabry--Perot mirror is modulated by optical carrier injection. Depending on the carrier recombination time, the width of the Nd:YVO4 laser pulses varies from 6 to 20 ps, as is typical for passively mode-locked Nd:YVO4 lasers.
