Abstract :
A further development of a new method for frequency control of the external cavity diode laser without the use of direct injection current modulation is reported. FM sideband heterodyne technique with AOM operating in a Raman-Nath diffraction mode as an external phase modulator and the atomic or the optical cavity resonances as the frequency references have been used to produce the error signals for highspeed servo-loop.
