Paper Abstract

Laser-induced damage thresholds of 2.2 picoseconds pulse for HR coatings prepared by Japanese optics makers were measured. The damage thresholds were compared with that of 10 nanoseconds pulse measured at last year. In picoseconds pulse, almost HR coatings had an average threshold of about 5 J/cm2. This meant that the damage thresholds of picoseconds pulse were unconnected to a little defects and/or contaminants in the coatings.
