ABSTRACT:
A device designed for generating a laser beam having a homogenized cross section has the following features:
a) a pulsed solid-state laser with an emission in a wavelength range of between 2 and 3 .mu.m,
b) a pulse energy of between 100 .mu.J and 1 J,
c) a transmission fiber made of a material transparent to the wavelength and having a length of at least 0.2 m and a diameter of between 50 and 1000 .mu.m,
d) an end piece made of quartz or sapphire and having a length of between 4 and 50 mm, the end piece following the fiber and having plane end surfaces arrange perpendicular to the longitudinal direction.
