Newport High Power Tunable Laser Repair

Common faults and maintenance ideas of Newport Laser Matisse C are as follows:

Output power decreases

Possible reasons: aging of laser crystal, failure of cooling system, circuit problems, pollution or damage of optical components.

Maintenance ideas: First use a power meter to monitor the power and select the degree of recovery. Check whether the laser crystal has obvious periodicity. If so, it needs to be replaced in time. Connect and check the cooling system to ensure that the cooling water is still and occasionally not still. If there is a problem, clean or repair the cooling system. Then use a multimeter to measure the voltage of the sensing circuit to check whether the circuit is normal. If there is a fault, repair or replace the relevant circuit components. Finally, output, clean the optical components, repair and protocol, and replace them if the components are damaged.

Beam quality deteriorates

Possible reasons: pollution or damage of optical components, changes in the working environment of the laser, and deviation of the optical path.

Maintenance ideas: Use a beam to check the beam quality and analyze the spot shape. Clean the optical components such as reflectors and beams to avoid damage and damage. Check whether the light-transmitting components are contaminated or change the environment. If so, clean or replace them. At the same time, check the working conditions of the beam, such as temperature, humidity and vibration, to ensure that the environment meets the requirements. If the optical path is found to be offset, the beam cavity needs to be readjusted to make the optical path normal.

System cannot start

Possible reasons: power failure, control system failure, channel path blocked, emergency stop switch not released.

Maintenance ideas: First check whether the main power supply and laser power supply are normally lit, check the power cable, fuse and control circuit board to ensure that the power supply is correct. At the same time, confirm that the emergency stop switch has been released. If the power supply is normal, check the control system to see if there are any abnormal alarms, confirm whether the software is running normally, and if there is a problem, repair or replace the relevant components of the control system. In addition, check the bridge path and remove short-circuited objects.

Frequency is unstable

Possible reasons: temperature control system problems, fluctuations in the laser operating environment.

Maintenance ideas: While checking the temperature control device, ensure that the cooling system is working properly so that the laser works within the appropriate temperature range. At the same time, check external environmental factors such as electromagnetic interference, vibration, etc. to minimize the impact of the environment on the laser.

Severe heating

Possible reasons: current overload, cooling system failure.

Maintenance ideas: Use an ammeter to measure the current to confirm whether it is overloaded. If it is overloaded, adjust the parameters or check the load equipment. At the same time, check the cooling system, including the flow and temperature of the water cooling unit and whether the cooling channel is blocked, clean the cooling channel, and replace the relevant parts of the cooling system if necessary.
