M. Nenchev et E. Stoykova, INTERFERENCE WEDGE PROPERTIES RELEVANT TO LASER APPLICATIONS - TRANSMISSION AND REFLECTION OF RESTRICTED LIGHT-BEAMS, Optical and quantum electronics, 25(11), 1993, pp. 789-799
The optical properties of the interference wedge are analysed for the
case of restricted laser beam illumination. By further development of
Brossel's method, equations describing this case are derived and used
to calculate the reflected and transmitted beam profiles for typical i
ntracavity laser beam diameters (0.2-0.6 mm) for Gaussian and uniform
intensity distributions. In particular, the experimentally observed fo
rmation of bright fringes outside the beam impact area at resonant wav
elengths is explained. Some useful dependencies concerning the wedge r
eflection and transmission for laser applications are obtained and exp
erimentally demonstrated.
