This is obtained by beating the ML frequency with the harmonic of the repetition rate of a 1560nm frequency comb (FC). We find a frequency noise PSD <; 10Hz 2 /Hz (-95dBc/Hz) at 100kHz from the carrier, limited by the noise of the QCL current driver. We also show that it is possible to actively phase-lock the QCLpumped ML to the FC repetition rate harmonic by controlling the QCL drive current.Show less >
