A Compact and Portable Laser Radioactive Decontamination System Using a Fiber Laser and a Polygon Scanner

摘要

We designed a compact and portable laser radioactive decontamination system using a fiber laser and a polygon scanner. The fiber laser produced 15-W average power at a 60-kHz repetition rate. 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 exceeding 88500 mm/s.
