In industrial manufacturing and other professional scenarios,laser processing technology is the key to improve production efficiency,and lasers play an irreplaceable role as core components.When the laser enters the work site,it is necessary to create a comfortable and safe”home”for it to ensure its long-term stable and efficient operation.
So,how to create an ideal operating environment for lasers?Please take a look at this”New Home”Guide for Lasers.
Requirements 1: The Foundation is Solid and Resistant to Vibration and Disturbance
The laser is extremely sensitive to vibration, and any small vibration may cause changes in machining effect,affecting machining accuracy and finished product quality.
- Site selection principle:when installing the laser,it should be far away from large stamping machines,forging equipment,air compressors,hoisting equipment and other vibration sources.
- Basic requirements:need to laser installed on the optical platform, or integrated in the machining machine, to ensure that the”foundation solid.”It is best to make a special tooling fixture to be fixed in the machine.

Requirements 2: The Temperature is Constant, the Humidity is Suitable
- Temperature requirements: Most lasers require a constant temperature environment of 20 °C to 30 °C.Temperature fluctuations cause the internal components of the laser to expand and contract, change the length of the resonator cavity,and affect the stability of the output power and wavelength.Air conditioning system is recommended to ensure constant ambient temperature.
- Humidity requirements: Environmental humidity should be controlled between 40% and 60%。Excessive humidity will make the optical lens condensation,absorb laser energy lead to film damage,or even cause high voltage circuit short circuit;It is easy to produce static electricity and damage electronic components if it is too dry.
- Key point: Stable temperature and humidity is the basic guarantee to prevent the laser from”sweating “(condensation)or”fever”(overheating).

Requirements 3: Power Supply is “Pure” and Output is Stable
- Voltage stability: Voltage fluctuation should be controlled within±5%,severe voltage fluctuation may directly damage the power module and pump source.
- Low ripple interference: It is recommended to equip a regulated power supply or an isolated transformer to filter out sharp pulse and noise interference.
- Independent grounding: It must be equipped with a reliable and independent grounding wire . The grounding resistance is generally required to be less than 4 ohms.This is not only the guarantee of personal safety but also the basis of equipment anti-interference operation.

Requirements 4: Cool Protection,Efficient Heat Dissipation
When lasers work,they convert large amounts of electrical energy into heat,so an efficient cooling system is a key prerequisite for their stable operation.
- Cooling water requirements: Water-cooled lasers must use purified water,and conductivity and temperature must be monitored regularly.Poor water quality can cause corrosion,scaling,blocking the water cooling channel,affecting the heat dissipation effect.
- Environmental heat dissipation: The water-cooled unit or air-cooled system itself also needs a good heat dissipation environment to ensure that its inlet and outlet are unobstructed and there is no accumulation of debris around it.

Requirements 5: Electromagnetic Compatibility,Non-interference with Each Other
The masher itself can act as a source of electromagnetic interference (EMI) and may also be disturbed by other equipment.
- Keep away from interference sources: try to keep away from strong interference sources such as high-frequency generators and high-power radio equipment.
- Good shielding: the trigger signal line between the processing machine and the laser should be selected with good shielding performance(such as RF coaxial cable or shielded cable),and the wiring should be specified.The laser should be kept at a safe distance from sensitive equipment such as control computers and sensors,or electromagnetic isolation measures should be taken.

Requirements 6: Safety First, Compliance Legal.
This is an insurmountable bottom line for lasers to “live and prosper.”
- Laser protection: Physical barriers such as laser shields and fences must be set up,and laser safety warning signs must be posted in areas where the laser path may be exposed.The operator should wear protective glasses matching the laser wavelength.
△Laser Safety Marking
Carefully preparing a standardized “home” for a laser may seem like an upfront investment,but it is a crucial investment to ensure long-term stable operation,maximize performance,and avoid unplanned downtime.Before welcoming this “new member” into your home,make sure to use this guide to create an ideal home that is secure,clean,comfortable and safe.Only then can it be at its best and create lasting value for you.
Trailer for the Series
Covestro Huachuang Hongdu officially launched a series of articles on laser maintenance and maintenance.This series will cover seasonal maintenance,downtime maintenance and standard operation,aiming to provide users with comprehensive maintenance guidance and help lasers achieve long-term stable operation.Please look forward to it.
