Paper Abstract

In the following rows a limitation device of the incident laser power in an optical system will be described, to prevent the destruction or the spoil of the captor situated in the extremity of the system. This device is based on the second order non-linearity of an inserted medium in the optical system used to obtain a beam geometry modification, for incident powers which exceeds a certain threshold, which will lead to the defocalization of the entire optical system and to the decrease of the incident light power on the captor.
