Will the laser marking machine get hot when it works continuously for a long time? Some time ago, the editor met a Ms. Wu from Jiujiang, Jiangxi Province, who consulted the editor on the price of laser marking machines and related issues on the Internet. Ms. Zhang opened her own jewelry store. Knowing that the laser marking market has been relatively hot in recent years, Ms. Zhang believes that this is a new profit growth point, so she wants to buy one for her own processing. So will the "laser head" of the laser marking machine work continuously for a long time will heat up? I will explain it to you today.

First of all, let's take a look at the working principle of the laser marking machine: the laser marking machine uses a laser beam to make permanent marks on the surface of various substances. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to engrave exquisite patterns, trademarks and words. The laser beam is manufactured by a laser: the pump light emitted by the pump source is coupled into the gain medium through a mirror. Since the gain medium is a rare-earth element doped fiber, the pump light is absorbed and the photon energy is absorbed. Rare earth ions undergo energy level transition and realize particle number inversion. The inverted particles pass through the resonant cavity, transition from the excited state back to the ground state, release energy, and form a stable laser output. This process does not generate any heat, so the laser marking machine will not generate heat if it works continuously for a long time.
