Notes on the two major precautions for fiber laser marking machines to prevent fiber breakage

The pump source and laser head of the laser system They are connected by optical fiber. Users should ensure that the bending diameter of the optical fiber is greater than 300mm during use or transportation. Severe bending will cause the fiber to break and the laser system to not work properly.

Prevent dust pollution

When the optical fiber access port of the power supply and laser head is not connected to the optical fiber, the protective cover provided with the system must be installed to prevent external dust from contaminating the internal optical components. .

When the optical fiber is not connected to the power supply and laser head, the protective cover provided with the system must be installed to prevent contamination of the optical fiber end face. (If dust has adhered to the optical fiber end face, an ear cleaning ball should be used to clean the optical fiber. Blow and wipe the end face clean. If the contamination is serious, wipe it clean with dust-free paper dipped in a mixture of alcohol and ether). Failure to install the protective cover will cause contamination of the internal optical components and fiber end faces, resulting in the entire laser system not working properly and voiding the warranty. Regarding avoiding condensation, preventing condensation on the laser crystal and LD cavity surface

The laser system is prohibited from working in a high-humidity environment. Customers should ensure that the ambient humidity is less than 60°C. When the temperature difference between the laser crystal temperature and the ambient temperature is too large (more than 10 degrees), it may cause condensation on the laser crystal. Condensation will cause the laser system power to decrease or be damaged.

Therefore, when the ambient temperature is much higher than the set temperature of the water tank (more than 10 degrees), it is strictly forbidden to operate the laser system with the water cooler on and the laser head not working. In this state, it is recommended to use the following steps to operate:

When starting up, first turn on the chiller, wait until the temperature of the chiller is lower than 30℃, start the power supply and slowly adjust the current to about 10A; When the temperature of the refrigerator is displayed at the operating temperature (about 18°C), slowly adjust the current to the operating current (about 35A).

When shutting down, first slowly reduce the current to about 10A and stop the power output, turn off the power, and then turn off the water cooler as soon as possible. If you do not work at the maximum current, you can increase the cooling temperature of the refrigerator appropriately (but not higher than 25°C). Be sure to use the laser system equipment in the specified environment (the operating environment in the south should be equipped with air conditioning). YAG laser is a solid-state laser with a wavelength of 1.064um in the infrared light band. It uses a krypton lamp as the energy source (excitation source). ND: YAG (Nd: YAG laser. Nd (neodymium) is a rare earth element, and YAG stands for yttrium aluminum pomegranate Stone, whose crystal structure is similar to ruby) is used as a medium for generating laser light. The excitation source emits incident light of a specific wavelength, which causes the working material to undergo mass inversion and releases the laser through energy level transition. The laser energy is amplified, shaped and focused to form a laser that can be The laser beam used.

Although the lamp-pumped laser marking machine is a very stable equipment. However, some minor faults may occur when customers do not pay attention to details. Let’s take a look at the two most common faults: Fault 1. The laser intensity decreases and the marking is not clear enough. Fault 2. The krypton lamp cannot trigger fault 1. Treatment methods: 1. Whether the laser resonant cavity has changed; fine-tune the resonant cavity lens. Make the output spot the best; 2. The acousto-optic crystal is offset or the output energy of the acousto-optic power supply 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 deviates from the center: adjust the laser; 4. If the current is adjusted to about 20A and the light sensitivity is still not enough: the krypton lamp is aging, replace it with a new lamp. Solution to fault 2: 1. Check all power connection lines; 2. The high-voltage krypton lamp is aging, replace the krypton lamp of the laser marking machine.
