Characterization of the laser induced damage threshold of mirrors in the ultra short pulse regime by Aaron von Conta Hochschule München, 2010 Abstract A semi automated setup for measuring the laser induced damage threshold of mirrors was developed. We utilized a change in the scattering behavior of the sample as indicator for damage. Currently we can measure up to fluences of 16 J cm 2 at a center wavelength of 780 nm, a spectral width of 50 nm [FWHM], a repetition rate of 500 Hz or 1 kHz and a pulse duration of 60 fs. We evaluated the involved statistical and systematic errors and concluded an uncertainty of the less than ±5% for the fluence calculations on the sample. Measurements were reproducible on different days with different calibration settings. Basic comparative studies on different in house coated mirrors were done. They will be used in the future to optimize the design and coating process in order to manufacture higher damage threshold optics. i
