title: Optical multipass matrix systems.
abstract: Large relative aperture three- and four-objective multipass matrix systems ensuring the longest optical path length in an absorbing medium have been developed for high resolution laser spectroscopy. In these systems the images are formed on the field mirrors as compact rectangular matrices with a controlled amount of lines and columns. The number of passes may reach 500 for mirrors with high reflectivity layers. Having a simple construction, the matrix systems provide high optical and operational features. In view of their capacities the matrix systems are new generation multipass systems.
