End-Pumped laser marking machine of working principle
1. Pumping Process:
The pump diode emits 808nm near-infrared light, which is coupled into the laser crystal (e.g., Nd:YVO₄) through the end face, exciting the crystal to generate 1064nm laser light.
2. Resonant Amplification:
The laser oscillates and amplifies within the resonator cavity, forming a high-energy-density pulsed or continuous laser beam.
3. Beam Control:
The galvanometer system deflects the laser beam according to the preset pattern, focusing it onto the material surface via an F-theta lens.
4. Material Interaction:
The laser energy causes surface vaporization, oxidation, or color changes, resulting in a permanent mark.
5. Technical Features:
- High efficiency of end-pumping, superior beam quality (M² close to 1), outperforming side-pumped and fiber lasers.
- Narrow pulse width (nanosecond level), suitable for fine marking.
