Abstract

The performance of a coupled-cavity mode-locked KCl:Tl color-center laser is investigated when an erbium-doped fiber having an enhanced spatial nonlinearity is included in the control cavity. Examination of their interferometric autocorrelations leads to the conclusion that the pulses emerging from such a laser system are significantly frequency chirped owing to self-phase modulation in the fiber. By using various lengths of glass rod as simple anomalously dispersive elements in intracavity or extracavity configurations, it is possible to compensate for the observed chirp and reduce typical pulse durations from 140 to less than 90 fsec.
