Paper Abstract

Injection locking is a useful technique for amplifying the output power of a tunable external cavity diode laser. The injection-locked output retains the spectral properties of the injected signal while offering high powers. A self-aligning injection-locked system is demonstrated that uses a chirped external cavity diode laser as the master laser. A gain of 51.8 dB is demonstrated with injection-locked output powers greater than 62 mW The amplified linear frequency chirp of 800 MHz in 4 ?s is measured and shows no deviation from the frequency chirp of the master laser. The high gain and ability of the injection-locked output to follow the rapid tuning of the injected source make it an excellent amplification technique for applications requiring higher powers with fast tuning.
