Abstract

Nonlinear optical devices, such as harmonic generators, provide a means of extending the frequency range of available laser sources. In this paper we report on a novel concept for scaling the output power of frequency doubled Nd:YAG lasers. Conceptually, the laser consists of multi oscillators, which are placed in a common resonator. The frequency doubler is an etalon shaped nonlinear crystal with dichroitic coatings. The second harmonic generated in different oscillators is coaxially superpositioned.
