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. His book, Dye Lasers, is considered a classic in the field of tunable lasers.
In addition to his pioneering work on the dye laser, Schäfer also made important contributions to femtosecond lasers and the application of these lasers in plasma physics.
