A compact and portable laser radioactive decontamination system using passive Q-switched fiber laser and polygon scanner.
Abstract
We designed a compact and portable laser radioactive decontamination system using a passive Q-switched fiber laser and a polygon scanner. The passive Q-switched fiber laser produced average power of 15\u202fW\u202fat a repetition rate of 60\u202fkHz. The scanner system contained a 12-sided spinning polygon mirror driven by a DC motor. By varying the spinning speed of the polygon mirror, we achieved a processing speed of up to 88,500\u202fmm/s. This system was demonstrated to be very efficient for radioactive decontamination on surfaces of various metals: stainless steel, brass, iron, and aluminum.
