Laser-material interaction exists a threshold power, only the laser power reaches the threshold car keys laser engraving machine, physical processing can begin. Laser marking threshold magnitude kW power in general. For high-reflectance surface or a material difficult to be processed, the pulse peak power required to reach a level above 10kW. But for most materials marking applications, pulse peak power of several kilowatts to meet their needs. Another key parameter is the pulse energy laser engraving machine, typically on the order mJ. Pulse length of time is a very important characteristic of the keyboard keys laser engraving machine, because it determines the action of heat and material time, have a significant impact on the quality of identity. Typically the length of time required between pulses 10 ~ 200ns. Pulse frequency is the number of pulses per second (in Hz), the typical laser marking systems operating frequency range of 20 ~ 80kHz. The average power is determined by the pulse energy and pulse frequency, average power value represents the total energy of the laser can provide. Fault 1: laser intensity decreased, marking the solution is not clear enough: a laser resonator is change; fine-tune the resonant cavity lenses. The best spot of the output; two acousto-optic crystal sound and light power output offset or low energy; adjust the sound and light crystal position or increase the sound and light power supply current; 3 into the off-center laser galvanometer: adjust the laser; 4. If the current is adjusted to about 20A is still sensitive and strong enough: krypton lamp aging, replacement lamps. Fault 2: krypton lamp can not be triggered (see NTP power usage manual) car keys laser engraving machine, laser engraving machine, Xixiang, fiber laser engraving machine provided by Dongguan Jun Laser Equipment Co. crown.
