Lidaris calc is a friendly tool with useful formulas designed for laser community.
LIDARIS Calc is a free app that helps estimating laser fluence or irradiance as well as scaling of damage threshold in optical materials for different pulse durations. You can do this by providing intuitive parameters such as laser beam diameter, laser pulse energy or average power and repetition rate. It might be very useful for rough estimations when standing in front of optical table or designing new optical scheme. By using this app you will gain confidence helping to prevent laser damage in optics with known laser-induced damage threshold (LIDT). Users of this app also get one free consultation with Lidaris laser damage testing experts.
