An. Dharamsi et al., REDUCTION OF EFFECTS OF FABRY-PEROT FRINGING IN WAVELENGTH MODULATIONEXPERIMENTS, Applied physics letters, 72(24), 1998, pp. 3118-3120
One of the factors limiting the sensitivity of wavelength modulation e
xperiments is the fringing that is created by inadvertent multiple ref
lections between parallel optical surfaces in the apparatus. It is sho
wn that the effects of this ''etaloning'' can be countered by using de
tection harmonic orders greater than the second. A theoretical basis f
or the effect is presented and compared with experimental results obta
