Abstract
A multimode laser can instantaneously generate a carrier frequency of significantly wide band. The proposed systems, composed of a free-runn ing multimode laser diode, an optical spectrometer, and a computing sy stem for fast Fourier transformation, can easily provide the potential for ultrahigh resolution of the order of 10 mum without scanning freq uencies as in frequency-domain reflectometers of either the continuous ly or the stepwise-swept variety.
