Abstract

Chirped mirrors as they were used in Ti:S lasers have the advantage of nearly constant group delay dispersion (GDD) over an extremely large bandwidth, an issue specially important at pulse durations in the sub-20 fs region. The authors have found, however, that a major limitation to the use of chirped mirrors in Cr:LiSAF and Cr:LiSGaF oscillators is their relatively high losses. Therefore, GT-mirrors providing more GDD and less losses are much better suited for the above systems. The authors measured transmission losses of GT-mirrors to be below 0.01% (vs. 0.2-0.5% for chirped mirrors). As the scattering losses scale with the field penetration depth, the GT-mirrors also exhibit about 50% less scattering than chirped mirrors. Recently, this authors reported the development of the first prismless Kr+ pumped KLM Cr:LiSGaF laser, delivering 47 fs pulses at 100 mW of output power. Here, they carried out measurements of the GDD of both, the active medium and the dispersive mirrors, in order to optimize the cavity for even better results and to get more insight to GT-mirror dispersion controlled systems.
