Fritz Peter Schäfer (15 January 1931 – 25 April 2011) was a German physicist, born in Hersfeld, Hesse-Nassau.
In this book the chapter written by Schäfer gives an ample and insightful exposition on organic laser dye molecules in addition to a description on the physics of telescopic,[3] and multiple-prism,[4] tunable narrow-linewidth laser oscillators.
In their original experiment Schäfer and colleagues[5] employed a ruby laser to optically excite various infrared organic dyes.
Schäfer et al. achieved high power outputs at a bandwidth of approximately 10 nm.
[9][10] Schäfer was Director of the Max Planck Institute for Biophysical Chemistry in Göttingen.
