Dt. Reid et al., Sonogram characterisation of picosecond pulses at 1.5 mu m using waveguidetwo photon absorption, ELECTR LETT, 36(13), 2000, pp. 1141-1142
Low energy picosecond pulses at 1.5 mu m have been completely characterised
by sonogram measurements based on mio photon absorption in a commercial In
GaAsP 1.3 mu m laser diode. The intensity and phase of pulses with 12pJ ene
rgy are in excellent agreement with those obtained from an independent freq
uency resolved optical gating characterisation.
