Overview of the Direct Diode Laser
1. Direct Diode Laser
Laser means the equipment to generate powerful light by amplifying light
(electromagnetic wave) or means this light itself. In direct diode laser, diode laser (LD)
can be applied to the heat processing directly without passing through a crystaline
body such as YAG and YVO
4
.
The laser wavelength generated in this laser equipment is 915 nm of near infrared
rays that are invisible to the human eye. Most of laser equipment for laser
processing belongs to class 4 laser that is the most hazardous in the classication
of laser products specied in JIS. When the laser light greets the eye, it is focused
by crystalline lens and reaches the retina, thereby inviting a loss of eyesight. Do
not look at the laser light in any case. Because both beams and scattered light are
hazardous, do not touch or look at them.
To check where invisible laser is irradiated on the workpiece, red guide light is
generally mounted in the laser equipment. When the output unit is provided with a
CCD camera, cross lines are generally displayed on the monitor and the cross point
of these cross lines is an irradiation point. In this laser, a red point appears on the
workpiece when guide light is output.
