The UV laser marking machine is composed of working material, pump source and optical cavity. It is also a solid material used as a working substance laser. Under the action of the pump source, the working material undergoes an inverse distribution of particle numbers, which becomes the active material, thereby amplifying the laser beam. More importantly, part of the amplified beam is fed back to participate in the excitation, and then the resonant cavity oscillates, and the laser can be generated after certain conditions are met. So what’s the applications of UV laser marking machine, let's find out.
