Research Abstract

We experimentally demonstrated that the excess phase noise of an external cavity diode laser (ECDL) can be efficiently suppressed by phase-to-amplitude noise conversion and filtered optical feedback techniques. We have observed that the phase noise of an ECDL was suppressed more than 40 dB and reached the shot noise limit from 15MHz using the above-mentioned technique. This opens a new way to reduce the phase noise of diode lasers. We generated second harmonic light using a enhancement cavity. This allows an conversion efficiency of 25% and produces an output power of up to 10 mW at 540 nm.
