Abstract
This laser beam processing apparatus includes a fiber laser oscillator, a laser beam branching unit, a laser beam injecting unit, a fiber transmission system, a laser beam irradiating unit, a processing table, etc. Based on a fiber laser beam oscillation-outputted from the fiber laser oscillator, the laser beam branching unit executes simultaneous multi-branching from the fiber laser beam into a plurality of branched laser beams. The laser beam injecting unit injects the branched laser beams respectively into optical fibers for transmission and the laser beam irradiating units condense and apply the branched laser beams from the optical fibers for transmission respectively to processing points.
Claims6
A laser beam processing apparatus comprising:
- a fiber laser oscillator having an optical fiber configuration that is adapted to employ a core containing an emission element as an active medium and to oscillate and output a raw laser beam having a predetermined wavelength by exciting the core using a predetermined excitation beam;
- a laser beam branching unit that branches the raw laser beam created by the fiber laser oscillator into a plurality of branched laser beam simultaneously or non-simultaneously;
- a laser beam injecting unit that injects the branched laser beams obtained from the laser beam branching unit into an end face of an optical fiber for transmission;
- and
- a laser beam irradiating unit that condenses and applies the branched laser beams exited from another end face after propagating the optical fiber for transmission.
