Paper Abstract

We report mode-locked laser operation of a diode-pumped Nd:Lu:YLiF4 crystal. This new laser material allowed generation of pulses shorter than those obtained from the well-established laser medium Nd:YLiF4 in the same experimental configuration. The modelocking regime was obtained by introducing a very weak acousto-optical modulation with Kerr-lens-induced pulse shaping. A suitable negative value of the intracavity group-velocity dispersion was introduced to enhance the initiation and stabilization of the regime. Pulses as short as 4.5 ps were readily obtained, without troublesome optimization procedures. To allow comparison with previously reported results for Nd:YLiF4 systems, we review the importance of spatial hole-burning effects in modelocking operation.
