Common causes and solutions for impure color of laser stage lighting

Common reasons and solutions for impure color of laser stage lighting:
Laser crystal aging:
Cause: Laser crystal is an important component for generating lasers. It will age after long-term use, resulting in a decrease in output power, poor beam quality, and reduced color purity.
Solution: Check the laser crystal regularly. Once it is found to be seriously aged, it needs to be replaced with a new laser crystal.

Contamination of optical components:
Cause: The optical components inside the laser (such as lenses, reflectors, etc.) are easily contaminated with dust, oil, etc. during use, which affects the transmission of the beam and causes impure colors.
Solution: Clean the optical components regularly. You can use professional cleaning tools and cleaning fluids for cleaning. Be careful not to damage the coating of the optical components.

Unstable power supply:
Cause: Unstable or excessively fluctuating power supply voltage will affect the operation of the laser, resulting in unstable output power and color changes.
Solution: Use a stable power supply and add a voltage stabilizer if necessary.

Poor heat dissipation:
Cause: The laser generates a lot of heat when working. If the heat dissipation is poor, the temperature of the laser crystal will be too high, affecting the stability of the laser output and the color will also change.
Solution: Ensure good ventilation around the laser and clean the dust on the radiator regularly.

Laser internal circuit failure:
Cause: The circuit board or connecting wire inside the laser may fail, causing the laser to not work properly and the output beam to be unstable.
Solution: Have a professional maintenance person check and repair the laser internal circuit.

Other possible causes:
Laser medium gas leakage: For gas lasers, if the sealing is not good, it will cause the laser medium gas to leak and affect the laser output.
Laser vibration: Vibration in the external environment will also affect the stability of the laser and cause impure color.
Preventive measures:
Regular maintenance: Regularly inspect and maintain laser stage lighting to detect and solve potential problems in time.
Use high-quality power supply: Provide a stable power supply for the laser.
Maintain a good ventilation environment: Ensure good ventilation around the laser.
Avoid severe vibration: Avoid placing the laser in an environment with large vibration.
Recommendation:

Professional maintenance: If you cannot solve the problem yourself, it is recommended to contact a professional laser equipment maintenance person for repair.
Refer to the user manual: Carefully read the user manual of the laser stage lighting fixture to understand the correct usage and maintenance methods.
