Measurement of Linear or Elliptic Polarization State of Laser Radiation with Three-Grating Bolometers

Measurement of Linear or Elliptic Polarization State of Laser Radiation with Three-Grating Bolometers

The results of experimental analysis of polarization state of wide-aperture laser radiation of a neodymium generator with a three-grating platinum profile bolometer are shown. Signals of 48 bolometer elements of gratings have been recorded with multichannel high-speed and highly sensitive analog-to-...

M. Pogorelov, S. V. Safronov, B. V. Balkashin, V. P. Priz, I. A. Kohns, P. The results of experimental analysis of polarization state of wide-aperture laser radiation of a neodymium generator with a three-grating platinum profile bolometer are shown. Signals of 48 bolometer elements of gratings have been recorded with multichannel high-speed and highly sensitive analog-to-digit transformers and stored to computer. The direction angle of linear polarization of radiation has been measured with the root-mean-square deviation (RMSD) 0.52°, relative squares of semi-axes of polarization ellipse with the absolute RMSD 1.2*10-2 and their direction angles with the absolute RMSD 0.13°. The method of measurements considered can be used within a wide spectral band. Приводятся результаты экспериментальных исследований метода измерения состояния поляризации широкоапертурного лазерного излучения неодимового импульсного генератора трехрешеточным тонкопроволочным платиновым профильным болометром. Сигналы 48-ми болометрических элементов решеток регистрировались многоканальными быстродействующими и высокочувствительными аналогово-цифровыми преобразователями и запоминались в ЭВМ. Измерение угла направления линейной поляризации излучения производилось со среднеквадратическим отклонением (СКО) 0.52°, относительные квадраты полуосей эллипса поляризации – с абсолютным СКО 1.2*10-2 и углы их направления – с абсолютным СКО 0.13°. Рассмотренный метод измерения может быть использован в широком спектральном диапазоне частот.
