The matters needing attention(1)

To working current (about 35A).

When shutting down, first reduce the current slowly to about 10A and stop the power output, turn off the power,The matters needing attention

and then turn off the water cooler as soon as possible. If you are not working at the maximum current,

you can appropriately increase the refrigeration temperature of the refrigerator(but not higher than 25 ° C)

thus Be sure to use the laser system equipment in the specified environment (Southern operating environment should be equipped with air conditioning).

Lamp-pumped

firstly YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared light band.

so It uses krypton lamps as the energy source (excitation source). ND: YAG (Nd: YAG laser.

Nd (neodymium) is a rare earth element, YAG stands for yttrium aluminum Stone, crystal The body structure is similar to ruby.

As a medium for generating laser light, the excitation source emits incident light of a specific wavelength, which causes the inversion of the working substance.

The laser light is released through energy level transitions. The laser energy is amplified and shaped to focus.

Usable laser beam.

Although the lamp pumped laser marking machine is a very stable device. However, when customers use it, they may cause some glitches because they do not pay attention to details, so let’s take a look at the two most common Failure

1. The laser intensity decreases and the marking is not clear enoughFault

2,lamp cannot be triggered
Troubleshooting method
1. Whether the laser cavity changes; fine-tune the cavity lens. Make the output light spot the best;
2. The acousto-optic crystal is shifted or the output power of the acousto-optic power is low;
adjust the position of the acousto-optic crystal or increase the working current of the acousto- optic power supply;
3. The laser entering the galvanometer is off-center: adjust the laser;
4. If the current is adjusted to about 20A, the sensitivity is still not enough: The lamp is aging, replace it with a new one.
Troubleshooting method :
1. Check all power cables;
2. The high-voltage lamp is aging. Replace the laser marking machine lamp.
