Measurements of Intense and Wide-Aperture Laser Radiation Parameters with Thinwire Bolometers

Abstract

Measurement methods of parameters and characteristics of intense (up to several tens of kilowatts in continuous mode and up to several tens of kilojoules in pulse mode) and wide-aperture laser radiation with bolometric gauges have been considered. The bolometric gauges are able to work in wide spectral range, withstand high levels of laser power or pulse energy. The considered methods use bolometric grids, which are loop-through type gauges and consume a low part of laser radiation. The maximal size of input aperture of bolometric grids has no limitations. Non-linearities of bolometer transformation characteristics have been considered
