Single-mode Ti:sapphire laser with a Sagnac-Michelson standing-wave resonator — •Stefan Narr — Physikalisches Institut, Eberhard-Karls-Universitaet Tuebingen, Auf der Morgenstelle 14, D-72076 Tuebingen

The concept of a novel standing-wave laser resonator is presented. It allows for simultaneous operation of two independent single-mode laser oscillators. The Sagnac-Michelson type resonator consists of two sub-resonators which both contain the same laser crystal.

In this way the crystal's gain can be used with maximum efficiency. Both laser oscillators can be tuned independently within a range of several GHz. As only few intracavity elements are needed, the concept may allow for the construction of a compact and robust ''twin beam laser''.
