Abstract
Single-frequency diode lasers such as distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers have important applications in communications, spectroscopy, and frequency doubling. Especially for the latter application, high output power is needed, too. Some years ago, DBR lasers were presented emitting at 856 nm beyond 270 mW optical power.1 No progress has been reported since then. The disadvantage of DBR lasers is periodic nonlinearities in the L-I curve due to longitudinal mode hopping. In contrast, DFB lasers can operate in the same longitudinal mode over a large current range. Here, we will present DFB lasers emitting at 862 nm in a single transverse and longitudinal mode up to 300 mW.
