ABSTRACT:
A method and system for measuring small gain or losses in a laser cavity. The method includes placing a sample in a cell in a two beam system in which one beam polarized in one direction passes through the cell while the other beam of different polarization does not pass through the cell. The ratio of the two polarizations with the sample in and out of the cell in the system determines a measure of the effect of the sample on the system. The ratios are measured with the sample cell empty and then with the sample in the cell.
