Abstract

In this paper, optimized Gires-Tournois mirrors were designed. The mirror structure was composed of 38 alternating Ta₂O₅ and SiO₂ layers and could be regarded as two sections: high-reflectivity section consisted of a series of quarter-wavelength optical thickness stack and negative-dispersion section consisted of only 13 layers. The designed mirrors exhibit the desired performance. These mirrors were fabricated by use of ion beam sputtering. By use of such Gires-Tournois mirrors, dispersion of mode-locked fetosecond Ti:sapphire laser was compensated and 32fs pulse was obtained.
