Commercial grade AlGaAs based light emitting diodes (LEDs) have been characterized at 1054 nm for their nonlinear photoconductivity and effect of aging and used as a two-photon detector to record auto-correlation signals of ultra-short laser pulses. The lifetime of these LEDs is found to be $6 • 10
