How does a gas laser work
WebAug 16, 2024 · The CO2 laser is a gas laser And usually works with evaporation. Often, gas is supplied in the cutting head or near the point where the laser beam meets the workpiece. In contrast to evaporation, oxygen is fed with the brick cutting, which supports the cutting process by oxidizing the workpiece. WebMany gas lasers work with a glow discharge, exhibiting relatively low current density and power density, while other types have an intense arc discharge where the power density …
