Laser power output variation

1 Beam path

1. The components on the beam path block the laser beam;

2. The lenses on the beam path are contaminated or damaged;

Picture 2: Broken lens of the beam expander

3. The transmittance of the optical lens used to the 10.6/10.2/9.3 μ m wavelength is low;

4. The laser type is not suitable for application. The beam path is too long but if choose a laser source with low power ,it cannot meet the requirements.

2 lenses of the laser source

1. Output mirror contamination

Picture 3: Output lens burned due to contamination

2. The processed material exhibits high reflectivity to laser beam of 10.6um wavelength , cause the internal reflector of the laser source burned.

3 Heat dissipation

Poor heat dissipation of the lasers cause increased temperature, which results in a decrease in power output.

4 Laser Gas

The laser has been in use for a long time and CO2 gas is loss, resulting in power drop.
