First diode pumped cw ruby laser — Walter Luhs1 and •Bernd Wellegehausen2 — 1Photonic Engineering Office, Freiburger Str. 33 79427 Eschbach, Germany — 2Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover, Germany
Almost 60 years after Maiman's famous first laser, cw laser oscillation of ruby at 694 nm in linear and ring resonators is reported, pumped with a 1 W diode laser at 405 nm. The ruby laser operates at room temperature with a threshold of 200 mW. So far output powers up to 36 mW have been achieved. With the ring resonator highly coherent single frequency operation will be possible.
