1-on-1 Test

1-on-1 laser damage testing: well suited for fundamental research and investigations of optical polishing quality and minimization of optical coating defects.

1-on-1 test is one of the simplest of laser-induced damage threshold (LIDT) determination techniques well suited for quantitative optics manufacturing process (such as coating deposition and glass polishing) optimization. Even in cases when damage threshold does not change it is possible to extract useful feedback data about process quality by performing sofisticated analysis. Watch how it works on one of our tutorial video:

To perform 1-on-1 test procedure  the surface area is divided into a matrix of sites, which are well separated in space. A constant number of sites are irradiated with one preselected pulse energy and one pulse per site. For each site pulse energy and the state of site (damaged or non-damaged) is recorded. After the exposure the damage probability is calculated. Then the pulse energy is increased and the sequence is repeated for another test sites. During measurement pulse energy is increased until 100% damage probability is reached. Damage threshold is estimated from damage probability dependence on applied pulse energy by appropriate extrapolation models. This testing procedure is extremely time saving and benefits customer in many ways while it is:

  • easy to interpret,
  • quick and simple,
  • suitable for defect densities and different defect ensembles characterization and minimization.

LIDARIS provides 1 on 1 test in a very broad range of experimental conditions and offers our customers detailed measurement reports containing easy to understand statistical data.
