Measuring of Gaussian Beam Laser Pulse Parameters with Nonlinear Thin-Wire Bolometers
RESUMO
A measuring technique of coordinates of a distribution center, root-mean square radius of a beam, module of an angle of the linear polarization and radiation pulse energy of Gaussian laser beam with thin-wire platinum bolometers with a nonlinear transformation characteristic is justified. Analysis of errors of measured results is carried out. Two identical thin-wire bolometers are placed in some distance from the beam centre within its cross-section parallel each other in a vertical direction and two bolometers of similar nature are placed in horizontal direction. Bolometers are placed in the inclines of intensity distribution of a Gaussian beam outside of the main radiation energy.
