Understanding phase properties of multilayer dielectric mirrors: a long but
exciting road to the first chirped mirror design

According to Springer graduate textbook in physics entitled „Ultrafast
Lasers”, it was the invention of a „chirped mirror” by Szipőcs et al that
began a new era in ultrashort pulse generation. In my talk I will summarize
background knowledge on optical multilayer dielectric mirrors previously used
in ultrafast laser systems, my theoretical considerations and corresponding
computer modelling work on dielectric mirrors with second-order phase
properties and mention a few of my experimental results finally resulting in
the first practical chirped mirror design at the Institute for Solid State
Physics and Optics prior to my first trip to the Technical University of
Vienna in July of 1993. Since then, chirped mirrors became key components in
ultrafast lasers including mirror-dispersion-controlled oscillators,
chirped-pulse-amplification systems, pulse compressors or broadly tunable
100-fs pulse lasers or optical parametric oscillators, which oscillators are
the workhorses for nonlinear microscopy.
