Abstract:
A laser beam machining head comprising:one collimating optical system for making laser light into a parallel beam; a first reflecting mirror for reflecting part of the laser light made into the parallel beam by the collimating optical system to divide the laser light into two beams, a first divisional laser beam and a second divisional laser beam; a second reflecting mirror for further reflecting the first divisional laser beam reflected by the first reflecting mirror to form a space portion between the first divisional laser beam and the second divisional laser beam; one focusing optical system for focusing the first divisional laser beam and the second divisional laser beam onto a portion to be machined; and a tip machining portion of machining means disposed in the space portion between the first divisional laser beam and the second divisional laser beam coaxially with the laser beams.
