Chapter 4 Overall structures and maintenance
The integral machine is composed of five parts, namely, the control cabinet, cooling system,
power cabinet, laser and optics processing system.
The equipment can also be divided into five parts in terms of functions, which are:
1) Laser;
2) Laser power supply;
3) Optics system;
4) Controlling system;
5) Cooling system.
4-1 Laser
(1) Structure
The laser is a device that converts the electrical energy into the laser energy. This machine
employs Nd
3+
：
YAG Laser, consisting of the following parts:
a)
Pumping lamp
: it converts the electrical energy into the optical energy that can activate
the substances for laser processing. The machine adopts pulse xenon lamp with repetition
rate of XMC7-125. Both the electrode and quartz glass tube surface need to be cooled
during working.
b)
Laser crystal
: it converts the optical energy into the laser energy. This machine
employs the crystal ф8*145mm Nd
3+
: YAG as its working substance.
c)
Condensing cavity
: it focuses the light from the pumping lamp onto the working
materials.
d)
The optical resonant cavity
can provide optical feedback, allowing the laser to be
magnified to form high strength laser for output. This machine employs the plane and
parallel cavity made up of flat mirrors with ceramics as its medium. The full reflector’s
transmissivity is less than 0.4%, output reflecting mirror’s transmissivity is 85%.
e)
Other parts
: high voltage electrode, insulation base plate, positioning bracket, adjustable
diaphragm frame and laser holder.
