Optimized metrology for accurate laser damage measurements

Summary form only given. Laser induced damage threshold is linked to many factors such as the damage criteria, test procedure, pulse duration, spot size, and wavelength. This induces difficulty to make comparisons, or compilations of results and reach on an absolute measurement. This absolute measurement of laser damage requires a high level of sensitivity and a perfect knowledge of the apparatus characteristics. In this context we have upgrade the metrology of our set up to control and know the influence of each parameter on laser-induced damage threshold measurement.
