The purity of the cooling water is the main reason for ensuring the laser output efficiency and the service life of the laser concentrating cavity components. During use, be sure to check once a week that the conductivity of the internal circulating water is 30.5MW·cm, and replace the ionized water once a month. The conductivity of the newly injected water must be 32MW·cm, and see clearly the internal ion exchange production. If the color of the resin has changed, it is time to replace the resin when it is found that the resin has turned black. The equipment operator uses black paper to detect the output spot of the laser. Once spot unevenness or energy drop is found, the laser's resonant cavity should be adjusted in time to ensure the beam quality during use. Common sense of optical safety protection, special laser protective glasses for 1.064mm wavelength must be worn during work. Note: When the strong laser is directly irradiated to wood and other flammable products, an open flame will be generated. During the debugging process, a black metal material with good absorption performance should be placed on the light path of the laser output as a beam terminator to prevent fire accidents; laser adjustment It must be carried out by specially trained personnel, otherwise it will cause damage to other components on the optical path due to laser misalignment or polarization adjustment. Therefore, the use of lasers is not very simple. It is one thing to use them well. In addition, they must be checked to ensure that they can work normally.
