From: Automated verification of countermeasure against detector-control attack in quantum key distribution
A modified setup for testing detector control under pulsed blinding. BPL, blinding pulse laser [1552Â nm, 40Â mW, Allwave Lasers SWLD-1550-100-PM(DBF)]. The pulse generator drives BPL directly and induces long laser pulses. The pulsed laser (PL) is also driven by the pulse generator directly and emits a relaxation-limited short laser pulse with 240Â ps FWHM delayed in respect to the start of the BPL pulse. The counter typically accumulates clicks over 1Â s for each data point
