Abstract :
Low energy picosecond pulses at 1.5 μm have been completely characterised by sonogram measurements based on two photon absorption in a commercial InGaAsP 1.3 μm laser diode. The intensity and phase of pulses with 12 pJ energy are in excellent agreement with those obtained from an independent frequency resolved optical gating characterisation
