The theory of the multiple-pass cell based on the use of
retroreflectors is presented. As a result of this study, it is
shown that it is possible to construct an enhanced White cell with zero
geometric loss. Starting from theoretical considerations of the
design of a new monolithic multiple-face retroreflector, a
multiple-pass cell is proposed. Ray-tracing simulations indicate
that this cell is easy to align and has zero geometric loss over a very
long optical path.
