1. Make sure it is the abnormal sound of the laser fan, not the abnormal sound of other equipment;

2. Check whether there is any other matter in the back cover of the laser;

3. Check whether there is abnormal sound of the laser caused by installation;

1. Check whether the power connection is normal;

2. Replace the power supply;

1. Check whether the control software is GUI software;

2. Check the control mode setting and select the corresponding internal control or external control mode.

3. Check whether the control line connection is normal.

A laser is a device that operates based on the principle of laser amplification. In the amplification medium (also known as the excitation medium) used by lasers, when the particles excited by external energy reach a critical value or above, spontaneous radiation is generated. These spontaneously emitted photons are in phase with the incident photons (laser) and emitted vertically outward, forming enhanced light.

The main components of a laser include light sources, mirrors, amplification media, optical resonators, and other components. When excited by a power source or other excitation means, the atoms at the light source begin to generate stimulated radiation in the excitation medium, using their energy to emit photons. A reflector can continuously reflect photons in a resonant cavity, amplifying the medium and increasing the intensity of light

1. If installed lifting Z-axis, check the accuracy of each movement of it and whether it is in focus;

2. Check whether the lens (galvanometer, field lens, beam expander) is dirty;

3. If using a high-power laser, please ensure that the lens material can withstand the high-power laser. It is recommended to choose a galvanometer and field lens made of quartz.

1. Please check whether the laser parameters are set normally;

2. Please check whether the power to the laser meets the requirements

3. Check whether the laser output head is polluted; the optical path is blocked

4. Use the "GUI" software to control the laser light output and test the power;

1. First use the RS232 cable to correctly connect the laser to the computer, and then use the internal control mode of our GUI software to control the laser to check the light output;

2. If the laser still cannot emit light, please contact our after-sales staff, and with the assistance of our staff, use the CRT to read the relevant information to check whether the self-locking is caused by too many alarms. If the laser is self-locking, Please unlock it to see if it can be recovered (JCZ software usually prompts a "system failure" alarm);

3. If unlocked still cannot recovered, it is recommended to return the machine to our company.

Lasers can be classified based on five aspects: gain medium, pumping method, output wavelength, output power, and operating mode. The specific classification method is as follows:

1. According to the different gain media, lasers can be divided into solid state lasers, gas lasers, liquid lasers, and free electron lasers. Solid state lasers can be further divided into fiber lasers, semiconductor lasers, all solid-state lasers, and hybrid lasers. The gain medium enters the excited state through an external energy source. In most lasers, this medium is composed of a group of atoms that are excited into this state using an external light source or electric field, providing energy for the atoms to absorb and transform into an excited state. The gain medium of a laser is usually a material with controlled purity, size, concentration, and shape, which can amplify the beam through the stimulated emission process described earlier. This substance can be in any state, such as gas, liquid, solid, or plasma.

2. According to the different pumping methods, lasers can be divided into optically pumped lasers, electrically pumped lasers, chemically pumped lasers, thermally pumped lasers, and nuclear-pumped lasers. Generally speaking, different types of pump sources are adapted to the different absorption wavelengths of laser crystals.

3. According to the different output wavelengths, lasers can be divided into infrared lasers, visible lasers, ultraviolet lasers, and deep ultraviolet lasers. Materials with different structures have different wavelengths of light that can be absorbed. Therefore, in fine processing or different application scenarios, we need to use lasers with different wavelengths to meet the needs of different materials.

4. According to the different output powers, lasers can be divided into low-power lasers, medium-power lasers, and high-power lasers. Lasers with different powers are suitable for different application scenarios.

5. According to different operating modes, lasers can be divided into continuous lasers and pulse lasers. Pulse lasers can be further divided into millisecond lasers, microsecond lasers, nanosecond lasers, picosecond lasers, and femtosecond lasers. Lasers can operate in a continuous or pulsed manner, depending on whether their power output is basically continuous over time or whether their output is presented in the form of optical pulses at a certain time scale.
