(5) the cooling system
3.1 Laser
3.1.1. Structure of Laser
Laser is laser device converts electrical energy into laser energy, the machine adopts Nd3 + :
YAG laser.
It mainly consists of the following parts:
(1) pump light (2) laser rod (3) focus cavity (4) optical resonator (5) Other accessories
Pump lamp converts electrical energy into light energy, "incentive" was carried out on the laser
work material. The machine adopts repetition rate pulsed xenon lamp, working electrode and
lamp quartz glass tube surface must be cooled, Laser rod can convert light energy into laser, the
machine adopts Nd3 + : YAG rods as work substance.
Optical focus cavity to focus light onto the working substance, the machine uses tight ceramic
cavity. The optical resonator to provide optical feedback, the laser can be enlarged to form a high
intensity laser output. The machine uses a parallel plane cavity by a plane mirror coated with a
high damage threshold dielectric film composition. When laser working, the power supply can
provide only about 3% of energy into laser, most is converted into heat energy and distributed on
the pump light, the laser rod and a condenser chamber. For the protection of the working parts,
then need to heat away. The machine adopts circulating demonized water lights, bars and cavity
cooling
In addition to the above main parts, there are the following parts:
(1) High pressure trigger, (2) the insulating base, (3) locating bracket, (4) 2d adjustable
diaphragm frame, (5) laser rack.
3.1.2. Cautions of operation and maintenance Laser machine is a light, mechanical, electrical
technology as one of the high-tech devices, Its more sophisticated equipment, operator must
have specialized knowledge and technology to work.
A. Optical resonator Two medium diaphragm of optical resonator Work parallel with the end face
of the laser rod strictly , So after optical resonator adjusted, user are not allowed to touch and
move freely mobilize. In addition, the optical surface must maintain clean, otherwise the
high-energy laser beam can damage of membrane layer, so don't open the laser cover. When the
laser output energy decline, should first check whether the medium diaphragm is clean, if there is
any dirt, available with lens paper or cotton wool cleaning fluid (50% anhydrous ethanol and ether
mixture, similarly hereinafter) wipe gently, and then check whether the cavity is disorder.
B. Cooling System: laser has an inlet, an outlet water tube, to connect cooling channels of light
and rod respectively. When either a poor water flowing, are likely to cause irreparable damage.
Each time you re-assembly, you should check water flowing to ensure the correct order to open

6
the laser. Ensure water flowing well before turning on the laser.
C. Lamp replacement: Pulsed xenon lamp is a consumable, the average life of the rated power
of the flash 106 times. To ensure working properly, when the lights worked full rated frequency
(approximately 106times), must be replaced when the energy dropping.
if xenon lamp because of other factors, damage, or actual life expectancy (performance is not yet
or still no energy output voltage to 500 v laser), should also change the xenon lamp.Due to the
transition on both ends of the xenon lamp glass sealing section of the strength is low, should be
especially careful when replacement, Steps as below:
1) Power off, cut off water supply and the release of the remaining charge on the storage
capacitor.
(2) Take down the lamp electrodes
(3) Take down the lamp gland, extracted xenon lamp carefully from the full mirror.
(4) With a cotton stick cleaning fluid to clean the casing.
(5) Check the appearance and size of new xenon lamps is in line with the requirement.
(6) Put lamp into the cavity, press the gland and mount on the electrode.
(7)Check the various parts of the seal after turning on water supply.
(8) Turn on the main power to check whether lamp discharging normally.
(9) With a single point of working conditions, check whether the laser output energy to meet the
requirements, if the output is not satisfactory, you need to adjust the resonator repeatedly.
(10) Cover the laser casing.
D. Nd3+: YAG rod operating: Nd3+: YAG rod is the core of the laser, install and use to be extra
careful.
Nd3 +: YAG rod end faces need parallel strictly, super clean, if found contamination, you must
clean indoor first, then processed by trained professional operator.
Take out the Nd3 +: YAG rod, paper or cotton wool moistened with lens cleaning solution (ethanol
and ether mixture of 50% each), gently erase the stain.
The cause of rod damages as below
a. Cooling water flow is too small or interruption, the light energy injected into the lamp, and
cause overheating of the lamp rod, the rod burst.
b. With a hard object collision, scratch, make end-face damage.
c. End surface with contamination, at high intensity laser burned through film.
d. When mounted stick too tight or uneven compaction pressure, due to internal stress caused by
excessive rod burst.
For this purpose, equipment operators do not open the laser cover generally, but also not allowed
to operate YAG rod, if found the end surface contamination, should be processed by trained
operators.
E. Maintenance of Focus cavity: With ceramic focus cavity with high reflectivity, and no need
maintain; generally do not allowed to take apart.
F. High voltage protection: to make the laser work, there are three kinds of voltage on the pulse
xenon lamp, be trigger voltage, 1.5 ~ 20000 v, pre-open circuit voltage 1700 ~ 2000 v, arc
discharge voltage about 500 ~ 1900 v.In addition, the lamp's electrode and other metal parts
should not be too close, at least over 15 mm

7
