Application of Dinghongrun optical elements in laser welding

The laser welding technology consists of an optical oscillator and a medium placed between the mirrors at both ends of the oscillator cavity. When the medium is excited to a high energy state, it starts to produce in-phase light waves and reflect back and forth between the mirrors at both ends, forming a photoelectric cascade effect, amplifying the light waves, obtaining enough energy and starting to emit laser. These laser beams have the characteristics of high concentration and single wavelength, and can provide welding, cutting, heat treatment and other functions after being highly concentrated. Dinghongrun Optical elements involved in laser welding include window piece lens , filter, reflector.
