Picosecond pulse operation of a dye laser containing a phase-conjugate mirror

We have demonstrated picosecond pulse operation of a synchronously pumped cw dye laser in which one of the conventional laser mirrors is replaced by an internally self-pumped BaTiO(3) phase-conjugate mirror. The laser pulses, of about 15-psec duration, were close to transform-limited. This Letter represents the first report to our knowledge of steady-state picosecond pulse operation of a laser containing a phase-conjugate reflector.
