Abstract :
We demonstrate the use of an injection-locked diode laser (792 nm) as the pump source for a continuous-wave (CW) Raman laser with Stokes emission at 1182 nm. Phase modulation of the master signal is imparted to the slave laser output in order to generate an error signal for phase/frequency locking via the Pound-Drever-Hall method. To illustrate the utility of this technique, we achieve the highest pump rate yet observed for a CW Raman laser (>90 times threshold) and compare the data to the existing theory. We also show how current modulation of the slave laser can eliminate the need for an electrooptic modulator in the system altogether.
