S. Slyusarev et al., FREQUENCY-MEASUREMENT OF ACCURATE SIDE-BAND OF AN OPTICAL FREQUENCY COMB GENERATOR, Optics communications, 135(4-6), 1997, pp. 223-226
The accuracy of the optical sideband generation of an optical frequenc
y comb generator (OFCG) was examined. The fundamental light and its se
cond harmonics from a YAG laser were used as input to the OFCG and as
pump light to an optical parametric oscillator (OPO), respectively. Th
e frequency between the +15th order OFCG sideband and the OPO signal l
ight was compared with that between the -15th order sideband and the i
dler. The frequency shift of the generated sideband was estimated to b
e smaller than 6 x 10(-13) at a frequency span of 276 GHz.
