Title:

HYBRID LASER PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2007/010783

Kind Code:

A1

Abstract:

Laser light L emitted from a laser oscillator (4) is guided by an optical fiber (12), constituting a light guide means (7), up to a processing head (6) having a channel (25) through which high pressure liquid is supplied by a high pressure pump (5). The high pressure liquid is ejected as a liquid column W from an ejection hole (24) of an ejection nozzle (23) provided at the lower end of the processing head (6). The optical fiber is exposed to the interior of the liquid channel and the forward end of a fiber core (12a) of the optical fiber is projected from a fiber clad (12b) and located in the proximity of the ejection hole. Laser light emitted from the fiber core is reflected at a first inclined surface (24a) of the ejection hole and guided to the liquid column, and then a workpiece (2) is processed. The laser light can be easily guided to the liquid column.
