Title:
LASER IRRADIATION DEVICE, LASER IRRADIATION METHOD, AND METHOD FOR MANUFACTURING MODIFIED OBJECT
Document Type and Number:
WIPO Patent Application WO/2007/114031
Kind Code:
A1
Abstract:
Provided are a laser irradiation device and a laser irradiation method, which
are suitable for a liquid crystal display device. The laser irradiation device
comprises a semiconductor laser element group (1A) having a plurality of semiconductor
laser elements (1) arranged therein for emitting laser beams of a wavelength
of 370 nm to 480 nm, optical fibers (2) for transmitting the laser beams emitted
from the semiconductor laser elements (1), a straight bundle (3) for holding
the optical fibers (2) straight, an optical adjustor (4) for shaping the laser
beams outputted from the optical fibers held by the straight bundle (3), into
a linear shape and for smoothing the top of the laser intensity distribution thereby
to output the smoothed laser beams, and an objective lens (5) for condensing the
laser beams outputted from the optical adjustor (4), as a linear laser spot on
an object. The semiconductor laser element group (1A) has a total irradiation
output value of 6 W to 100 W.
