How to solve the problem of co2 laser marking machine power attenuation? We know that laser marking machine is composed of a life limiting, in the work to a certain time will appear after the obvious change, the laser intensity as before.


We know that the laser marking machine is composed of a life limiting, in the work to a certain time will appear after the obvious change, the laser intensity as before, also is we often say that laser power attenuation phenomenon. Power attenuation effect on the work of the equipment is very large so how are we going to prolong the aging time?

1, check the krypton lamp life is out of date, if due to the timely replacement of the new;
2, cooling water tank water temperature and environmental temperature over 5 ℃, if exceeded, the timely adjustment of the normal;
3, if the anti - and output membrane fouling, should be promptly wiped clean, if not wipe clean in time for the new;
4, if the acoustooptic crystal acousto optical power output offset or low energy, timely adjustments to the acousto-optic crystal position;
5,laser into the mirror off center, adjusting the laser;
6, if the current is transferred to the 20A or not is still a photosensitive strong krypton lamp aging, suggest to replace the new lamp;
7, check whether the change of laser cavity resonator mirror: fine, make the output spot the best.

The several factors of laser marking machine output power attenuation
One,in our daily use of various laser processing equipment, will encounter some problems due to improper use and what happens, especially the fault output power of laser processing equipment attenuation, it often will seriously affect the marking effect. A variety of conditions and the following treatment we laser marking machine, laser output power equipment common attenuation for your reference, hoping to help the user to better use and maintenance of laser processing equipment,the laser marking machine price is reasonable.

The new equipment, the use of time is not long, because the output power of the laser attenuation:
Measurement of laser output power of the factory whether meet the technical index;
Whether the accuracy of adjustment to meet the requirements of resonant cavity;
The diaphragm is light leakage;

The acousto-optic switch insertion loss is within the specified range.
Two, after the use of a period of time, because the output power of the laser attenuation:
The laser cavity resonator mirror whether changes: fine, to spot the best output;
The anti - and output film or defacing;
Acousto-optic crystal acousto optical power output offset or low energy: adjust the acousto-optic crystal position;
If the cooling water tank water temperature and environmental temperature over 5 ℃;The krypton lamp service life has expired;
Laser into the mirror off center: adjusting the laser;
If the current is transferred to the 20A still photosensitive strong not: krypton lamp aging, the replacement of the new lamp.

Three, the output power of the laser is normal, but the laser beam can not play the role of marking:
The optical system adjustment is accurate;
Acousto optic switch is able to play a role switch;
D/A card control acousto optical output signal is 5V.

Four, optical switch can not play a due role switch laser:
The RF output power acousto optical power supply is normal;
The power switch is in the correct position;RF cable connection is reliable;Q switch optical surface has no fouling phenomenon.Five, not to cause the expected depth of marking:If the laser output power requirements;Close the power whether meet the requirements of acousto optic switch;Optical path adjustment is accurate;The beam expanding mirror position, direction adjustment is accurate;Lens surface has no pollution;Laser power output voltage of 28V is decreased, the laser output power decrease,the prospect of laser marking machine for sale is very good.
