A programmable control device of the amplitude and phase of the spectrum of light pulses from an optical melangeur

摘要

Device for controlling the amplitude and phase of the spectrum of light pulses at output of an optical mixer (m) carrying out the collinear interaction of optical signals coming from two channels (v1, v2), including: - on the above-mentioned channels (v1, v2), respectively two drawing rolls of pulses (s1, s2) extending the short light impulses produced respectively by two laser sources (l1, l2), -, on at least one of said channels (v1, v2), a programmable controller (p1, p2) for controlling the amplitude and phase of the signals coming from the above-mentioned drawing rolls of pulses (s1, s2), and - at the output of the said optical mixer (m), a compressor (c) of the pulses delivered by said optical mixture (m).
