Sample Ranking vs. Damage Threshold Criteria in Small Spot Size Laser Damage Testing

Source

Small spot size (3.5 mm) laser damage testing at 10.6 μn has been used on samples which consisted of metallic and metallic oxide coatings on polymeric substrates. Three degrees of damage were used to define damage thresholds. While absolute threshold values were different for each of the three levels of damage, sample ranking did not change. As long as consistency is maintained, the degree of damage used to define the damage threshold does not appear to be significant for small spot size testing for these samples, where the goal is to screen the effectiveness of a series of hardening concepts.
