Pulsed CO_2 laser-induced damage on BK7 disks

摘要

A comprehensive investigation of pulsed CO_2 laser interaction with BK7 disks was carried out. The samples were irradiated with 10 μs CO_2 laser pulses to measure laser-induced damage thresholds. Transmission characteristics were observed over a certain time interval. Damage morphology was monitored with scanning force microscopy. Thermal simulations allowed for the interpretation of the laser-induced damage process.
