LASER PROCESSING METHOD AND PROCESSING DEVICE BASED ON NORMAL LASER-INDUCED MATERIAL CHANGES Russian patent published in 2010 - IPC B23K26/38 

FIELD: electricity.

SUBSTANCE: pulse of ultrafast laser with picosecond or shorter pulse width is associated by time and spatially with a pulse of at least one auxiliary laser that differs from ultrafast laser. Auxiliary laser pulse is controlled in such a manner that it could change in time. In this process, material condition to be processed is changed reversibly using one auxiliary laser beam and changed irreversibly when auxiliary laser beam ultrafast laser beam are associated by time and spatially. Auxiliary laser generator includes electronic communication device which modifies laser beam pulse in time and focusing optical system for spatial association of ultrafast laser beam focal point generated by ultrafast laser generator with focal point of auxiliary laser beam associated with time and for focusing ultrafast laser beam and auxiliary laser beam.

EFFECT: increase in speed of ultrafast laser processing with ultrahigh accuracy.
