When the gas is excited externally by RF energy, its molecules absorb energy. The photon is amplified as it stimulates more photon emissions while it moves along the tube. The photons bounce along the tube between one mirror which is fully reflective and the other which is partially transmissive. When a critical mass is reached, a pulse of heat radiation is emitted to form the laser beam. The laser light is then focussed via lenses to produce precise marking energy.
Laser delivers precise performance.
Unlike other traditional coding and marking technologies, laser has no tooling that can wear over time. Once the operating parameters are set correctly, the laser system will apply codes consistently onto the products or packages. Permanent Images Laser produces marks by permanently changing the surface of substrates. The result is a crisp, indelible image that cannot be removed or altered. When a clean production line is essential, laser outperforms conventional methods.
