Abstract
A theoretical investigation of the possibility of achieving self-similar pulse propagation in a solid-state laser is presented. Limited group-velocity dispersion hinders true self-similar pulse evolution, but an intermediate regime that exhibits some of the characteristic features (and offers some of the benefits) of self-similar propagation can be reached. This regime of operation offers the potential to increase the pulse energy by at least an order of magnitude compared to energies obtained in the usual operation of Kerr-lens mode-locked lasers with anomalous dispersion. Ti:sapphire lasers that generate pulse energies as high as one microjoule and peak powers of ~100 MW should be possible based on this mode of operation.
Highlights
One of the routes to higher pulse energy is to operate the laser with normal net cavity group-velocity dispersion (GVD) [14]
The first experimental demonstrations of self-similar operation of fiber lasers produced 3 times larger pulse energy, and 5 times larger peak power, than the corresponding maxima obtained with stretched-pulse lasers
We briefly review the main issues and properties of a similariton laser, to provide context for the discussion of a solid-state version
