Two-photon absorption in a commercial InGaAsP 1.3 μm Fabry-Perot laser diode has been used for autocorrelation measurements of picosecond pulses at 1.5 μm with average power peak-power products as low as 0.15×10-3 (mW)2. The laser diode has also been observed to possess a sub-nanosecond electrical response suitable for optical thresholding applications
