1, temperatureAt room temperature, the absorption rate of metal materials is two at 20, when the metal temperature reaches the melting point and the absorption rate is 40~50%, the absorption rate can be as high as 90% when it is close to the boiling point.The square root of the direct current resistivity of the material…
1, laser input energy density. Methods for adjusting the energy density of laser irradiation:A, adjust the laser output energy (adjust the excitation voltage)B, adjust the spot size (adjust the focal length)C, change spot energy distribution (change the fiber type: peak output type -- a GI type optical fiber, ladder typ…
