A system of precise frequency modulation of laser radiation by an acousto-optic modulator, which makes it possible to stabilise the radiation power and simultaneously suppress the residual amplitude modulation to a level of 10{sup -8} of the total laser power at the third harmonic of modulation frequency (∼500 Hz), is presented. The use of this system for the Nd : YAG/I{sub 2} optical frequency standard and application of digital signal synthesis and processing methods provided a level of frequency standard instability as small as ∼10{sup -15} for ∼6 × 10{sup 4} s.
