20 years ago the first SESAM modelocked solid-state laser result was published.  Since then we have observed rapid progress in ultrafast solid-state lasers enabling many new scienctific and industrial applications. I have been actively involved at the frontier of this field for more than 20 years and can provide some more personal insight into how the field evolved.  I will start with a brief description of the status 20 years ago, then continue with the invention of KLM, the SESAM, and the frequency comb technique. Towards the end I will give a brief summary of the many different applications that have been enabled by this rapid progress in ultrafast solid-state lasers (such as material processing, frequency metrology, attosecond science and many others) and finally conclude with an outlook into the current research efforts and challenges.
