Emitting a specific wavelength can promote the energy level transition of the working substance to release laser, and the laser energy is amplified to form a laser beam for processing materials.

★CO2 laser marking machine: CO2 gas is filled into the discharge tube as the medium for generating laser, and high voltage is applied to the electrode to generate glow discharge in the discharge tube, so that gas molecules release laser, and the laser energy is amplified to form a laser beam, which is used for processing materials.

★ Semiconductor Side Pumped YAG Laser Marking Machine: The Nd: YAG medium is pumped by a semiconductor laser diode with a wavelength of 808nm, so that a large number of inversion particles are generated in the medium, and a giant pulse laser output with a wavelength of 1064nm is formed under the action of Q switch, with high electro-optical conversion efficiency.

★ Semiconductor end-pumped YAG laser marking machine: pump the semiconductor pump light (808nm) directly from the end face of the laser crystal and output it through the optical lens group to generate laser. Thereby greatly improving the linear light conversion efficiency.

★ fiber laser marking machine: The laser is directly output by optical fiber.

Two measures to prevent optical fiber breakage in fiber laser marking machine

The pump source and laser head of the laser system are connected by optical fiber, and the user should ensure that the bending diameter of the optical fiber is greater than 300mm during use or transportation. Severe bending will lead to fiber breakage and the laser system will not work normally.

Prevent dust pollution

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

When the optical fiber is not connected with power supply and laser head, the protective cover provided with the system must be installed to prevent the end face of the optical fiber from being polluted. (If dust adheres to the end face of the optical fiber, the end face of the optical fiber should be blown clean with an ear washing ball. If the pollution is serious, wipe it clean with a dust-free paper stained with a mixture of alcohol and ether. ). Failure to install the protective cover will pollute the internal optical components and fiber end faces, resulting in the failure of the whole laser system and loss of warranty. Study on preventing condensation on the surface of laser crystal and LD cavity

The laser system is forbidden to work in high humidity environment, and the customer should ensure that the ambient humidity is less than 60%. When the temperature difference between the laser crystal and the ambient temperature is too large (greater than 10 degree), the laser crystal may be dewed, which may lead to the power reduction or damage of the laser system. Therefore, when the ambient temperature is much higher than the set temperature of the water tank (above 10℃), it is strictly prohibited for the laser system to be in a state where the water cooler is turned on alone and the laser head does not work. In this case, the following steps are recommended:

When starting up, first turn on the water cooler, and when the temperature of the refrigerator is lower than 30℃, start the power supply and slowly adjust the current to about 10A; When the refrigerator temperature is displayed at the working temperature (about 18℃), slowly adjust the current to the working current (about 35A).

When shutting down, first slowly reduce the current to about 10A, stop the power output, turn off the power, and then turn off the water cooler as soon as possible. If it does not work under the maximum current, the refrigeration temperature of the refrigerator can be appropriately increased (but not higher than 25℃), and the laser system equipment must be used in the designated environment (air conditioning should be installed in the southern operating environment). YAG laser is a solid-state laser with infrared wavelength of 1.064um, using krypton lamp as energy source (excitation source), Nd: YAG (Nd: YAG laser. Nd (neodymium) is a rare earth element, YAG stands for yttrium aluminum garnet, and its crystal structure is similar to ruby) as the medium for generating laser. The excitation source emits incident light with a specific wavelength, so that the number of working medium particles is reversed, and the laser is released through energy level transition, which amplifies the laser energy, shapes and focuses, and forms a usable laser beam.

Although the lamp pump laser marking machine is a very stable equipment. However, when customers use it, they may cause some minor faults because they don't pay attention to details, so let's take a look at the two most common faults: 1, the laser intensity drops, and the marking is unclear; Fault 2: Krypton lamp cannot trigger fault1; Processing method: 1, whether the laser resonator changes; Fine tuning resonant lens. The output light spot is optimized; 2. The acousto-optic crystal shifts or the output energy of acousto-optic power supply is low; Adjust the position of acousto-optic crystal or increase the working current of 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 20 years, the light perception is still not enough: the krypton lamp is aging, so replace it with a new one. Handling method of fault 2: 1, and check all power connection wires; 2. The high-voltage krypton lamp is aging, and the krypton lamp of the laser marking machine is replaced.
