Do you know how to use laser light?

Laser beam quality is an important technical index for the propagation characteristics of Laser pointer in the whole space of laser beam. It conforms to ISO 11146 standard This parameter can be measured from several aspects of light propagation through different measurement methods. Some measurement methods are defined in the standard, All these are based on the beam profile, using CCD, notch, notch, etc. the definition has two basic requirements. The application of laser, according to whether the laser probe is in contact with the material that the laser acts on, is divided into two working modes: contact and non-contact. The fields of laser application mainly include six fields of industry, medical treatment, commerce, scientific research, information and military. One is the measurement of focused beam, The second is the measurement of collimated laser. In the latter case, the basic principle of operation is to focus the beam through the lens to form the waist position, and vice versa Formation of divergent beam. The measurement accuracy of M2 is determined by repeatedly scanning the calculation band and sharpening the long-term scattering at zero.
