F. P. Schäfer
Fritz Peter Schäfer (15 January 1931 – 25 April 2011) was a German physicist, born in Hersfeld. He is the co-inventor of the dye laser.[1][2] His book, Dye Lasers, is considered a classic in the field of tunable lasers.
In their original experiment Schäfer and colleagues[3] employed a ruby laser to optically excite various infrared organic dyes. These dyes emitted laser radiation in the 731-835 nm range. Schäfer et al. achieved high power outputs at a bandwidth of approximately 10 nm. Schäfer also experimented with laser dyes in the vapor phase under optical excitation.[4]
In addition to his pioneering work on the dye laser, Schäfer also made important contributions to femtosecond lasers[5][6] and the application of these lasers in plasma physics.[7][8]
