Abstract

In this paper, we report a new compact design of an external cavity diode laser system (ECDL) to combine high output power with high brilliance emission with broad area diodes. To achieve an excellent phase coupling to the external resonator one facet of the broad area diode is unreflection coated and the other facet is high reflection coated. The very compact laser design offers an output power of up to 500 mW with a sidemode suppression ratio better than 50 dB in both longitudinal and spatial singlemode operation.
