Reasons and solutions for the decrease of laser intensity of water cooled uv laser

1. Whether the position of the resonant cavity of the UV laser marking machine has changed due to long-term use, fine-tune each lens of the resonant cavity, so that the spot can achieve a high-quality effect.

  2. Check whether the output current of the acousto-optic power supply is low or the position of the acousto-optic crystal is shifted, increase the current of the acousto-optic power supply or correct the position of the acousto-optic crystal.

  3. Check whether the laser of the UV laser marking machine deviates from the center point after entering the galvanometer, and adjust the position of the laser light to return to the center of the galvanometer.

  4. If the current of the UV laser marking machine is adjusted to 25A and the processing effect is not strong enough, then it means that the krypton lamp is the problem, and the krypton lamp needs to be replaced.
