Use Of Crossed-beam Spectral Interferometry To Characterize Optical Pulses
MetadataShow full item record
Disclosed are an apparatus and methods for determining electric field characteristics of pulses. In one example, a method is provided in which an unknown pulse is propagated through a first optical fiber. A reference pulse is propagated through a second optical fiber. The unknown pulse and the reference pulse are directed out of the first and second optical fibers into a spectrometer. The unknown pulse and the reference pulse propagate along a pair of crossing trajectories through the spectrometer to form an interferogram. The electric field of the unknown pulse is determined by processing this interferogram.
