Field Distribution of Laser Beam on a Tilted Plane from the Transverse Plane

摘要

The field distribution on a plane tilted from one perpendicular to the propagation axis (transverse plane) is investigated. The field is approximated by Gaussian distribution except when the tilt angle is not too close to 90°. This paper experirnentally exarnines the extent to which the approxirnation holds. The results show that if the angle is srnaller than 70°, the field is well approxirnated by Gaussian distribution within an error of 10%.
