Optical fiber laser marking machine marking result is bad how to solve? Laser intensity drops, mark is not clear, the solution: 1 whether laser resonator changes; Fine tuning cavity lens. Make the output light is best; 2 acousto-optic crystal offset or low light output power energy adjustment acousto-optic crystal location or more sound and light power workflow to go in the galvanometer laser 3 off center: adjust the laser; If current transferred to about 20 a photographic still strong enough: krypton lamp aging, replace the new lamp. Other causes: first: the lens is too dirty, use cotton with a bit of alcohol, and then gently wipe the mirror; Second: the object of playing too fast, can reduce the target speed, thereby increasing filling density; Third: the power of the laser current power flow is too small, no open or open the power supply current or power supply current of power up; Fourth: laser module has to use fixed number of year, may be its service life, need to replace the laser module.
