Abstract
The visualization of interference fringes produced by the superpositio n of two different laser beams requires complex and costly demonstrati ons. This paper describes an experimental setup which (with the exclus ion of an inexpensive and easy-to-build pair of optical guides) uses c onventional laboratory equipment to detect the presence of the fringes .
