Precautions about the fiber laser marking machine two major to prevent Preventing optical fiber Fracture
The laser system pump source and the laser head by the optical fiber for connection, the user in use or in the process of transportation should ensure that the fiber bending diameter is greater than 300mm. bending serious will lead to fiber breakage and the laser system can not work properly.
Prevention of dust contamination
Power supply and laser head of the fiber optic access port in the state of not connected to the fiber, must be installed with the system to provide a protective cover, to prevent external dust contamination of the internal optical components.
The fiber optic must have the protective cover supplied with the system installed to prevent contamination of the fiber optic end face when it is not connected to the power supply and laser head (if the fiber optic end face has been adhered to the dust, the fiber optic end face should be cleaned by blowing with an earwash ball, and if the contamination is severe, it should be wiped with a dust-free paper moistened with a mixture of alcohol and ether). Failure to install a protective cover will contaminate the internal optics and the fiber endface, which will cause the entire laser system to fail to function properly and void the warranty. About Avoiding Condensation Preventing Condensation on the Laser Crystal and LD Cavity Surface
Prohibiting the laser system from operating in a high humidity environment, the customer should ensure that the ambient humidity is less than 60%. When the temperature difference between the laser crystal temperature and the ambient temperature is too large (more than 10 degrees), it may cause the laser crystal to condense, and the condensation will lead to power loss or damage of the laser system. Therefore, when the ambient temperature is much higher than the set temperature of the water tank (more than 10 degrees), it is strictly prohibited for the laser system to be in the state of turning on the water cooler alone without the laser head working. In this state, it is recommended to use the following steps to operate:
When the power is on, first turn on the chiller, wait until the chiller temperature display is lower than 30 ℃, start the power supply and slowly adjust the current to 10A or so; wait until the chiller temperature display is at the working temperature (18 ℃ or so), then slowly adjust the current to the working current (35A or so).
When shutting down the machine, first slowly reduce the current to about 10A and stop the power output, turn off the power, and then shut down the water cooler as soon as possible. If you do not work at the maximum current, you can appropriately adjust the cooling temperature of the chiller (but not higher than 25 ℃) be sure to use the laser system equipment in the specified environment (the southern operating environment should be installed air conditioning). YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared light band, using a krypton lamp as the energy source (excitation source), ND:YAG (Nd:YAG laser. Nd (neodymium) is a rare-earth group element, and YAG stands for yttrium-aluminum garnet, which is similar to ruby in its crystal structure) as a medium for generating laser light, and the excitation source emits the incident light of a specific wavelength, which induces the working substance to undergo a The excitation source emits a specific wavelength of incident light, which causes the working material to undergo inversion of the abundance, releasing the laser light through energy level jumps, amplifying the laser energy and shaping and focusing it to form a usable laser beam.
Although the lamp pumped laser marking machine is a very stable equipment. But when customers use due to not paying attention to the details and other reasons, may cause some glitches, then we look at the two most common: Fault 1, laser intensity decreased, marking is not clear enough Fault 2, krypton lamp can not be triggered Trouble 1 treatment: 1, the laser resonance cavity is not changed; fine-tuning of the resonance cavity lenses. Make the best output spot; 2, acousto-optic crystal offset or acousto-optic power source output energy is low; adjust the acousto-optic crystal position or increase the acousto-optic power source operating current; 3, into the vibrating mirror laser deviation from the center: adjusting the laser; 4, if the current is adjusted to 20A or so is still not enough to feel the light intensity: krypton lamp aging, replace the new lamp. Fault 2 treatment: 1, check all the power connection line; 2, high pressure krypton lamp aging, replace the laser marking machine krypton lamp.
