Abstract :
A new method for frequency stabilization of an external cavity diode laser without the use of direct injection current modulation is presented. A Pound-Drever FM sideband technique with AOM operating in a single pass Raman-Nath diffraction mode as an external phase modulator and atomic resonance as the frequency reference are used to produce an error signal for frequency locking of the laser diode to the resonances within caesium D2 spectral line.
