Abstract :
Physical and technical parameters are reported for a laser optical system that is used to cut and engrave. The laser optical system is formed by optical resonant cavity, reflector mirrors, beam expander, and a focal system. The assembly is part of an equipment to cut and engrave by laser via, which is called Ulyses, and was developed in the Laser Technology Laboratory at IMRE-University of Havana. Nd:YAG laser with 1064 nm wavelength is used to obtain 1 ms pulse with energy peak of 1.2 mJ. We have made several engraving with different sizes and wide line, with thicknesses from 0.5 mm to 3 mm in brass and alloying steel.
