The “light trap” set-up: a partially transparent mirror; a thin, weak absorber; two converging lenses; and a totally reflecting mirror. Normally, most of the incident light beam would be reflected. However, owing to precisely calculated interference effects, the incident light beam interferes with the light beam reflected back between the mirrors so that the reflected light beam is ultimately completely extinguished. The absorber completely sucks up the energy of the light. 

A perfect ‘light trap’ to improve efficiency of photovoltaic systems

Using mirrors and lenses, a light beam is steered in a circle and then superimposed on itself.
