FIELD: laser engineering.
SUBSTANCE: device for shaping uniform distribution of intensity of a laser beam in its cross section includes coaxially located in the direction of laser radiation: a hollow truncated photometric shaper (PMS) made in the form of a truncated cone, the inner surface of which is coated with a diffusely reflecting coating, a diffusely transmitting convex-concave lens, a biconcave lens. Herewith the said elements are coaxial.
EFFECT: technical result achieved at implementation of the proposed device is higher level of radiation intensity of the laser beam within the area of the outlet window (up to Emax=0,351 relative units) at a high degree of uniformity (0,96…0,99).
