MOPA laser solution provides one-stop processing service for the new energy industry

MOPA pulse fiber laser has received extensive attention and research as a new laser technology, and is increasingly used in laser marking, precision cutting, laser cleaning, dissimilar metal welding and other fields.

MOPA laser is an ideal solution for lithium battery cutting. With the development of intelligent and electrified automobiles, lithium batteries are upgraded to high energy density and high conversion efficiency. Under this background, the market's requirements for lithium battery processing equipment are constantly increasing. Low-power MOPAP can no longer meet the increasingly complex application scenarios. In the future, MOPA lasers will develop towards higher frequency, higher power, narrower pulse width and higher energy.

Application of high-power MOPA laser solutions in the new energy industry
JEZ's newly launched high-power MOPA laser solution uses the independently developed MOPA500-2000W pulsed single-mode laser. This series is the first high-performance MOPA laser in China to use a single-cavity high-energy method. The maximum average power can reach 1000W and 2000W, and the maximum single pulse energy can reach 100m". Multiple power options, compact structure, easy operation, maintenance-free, can be directly integrated into user equipment, and is an ideal laser source for lithium battery precision material processing and other industries.

Cleaning application
In cleaning and surface treatment, MOPA500-2000W pulsed single-mode laser shows unique advantages. It can be used for pole piece cleaning, blue film (paint) cleaning, battery pole injection hole cleaning, battery aluminum shell cleaning, etc. No matter which process has strict requirements for the application of laser technology, JEZ Laser has conducted in-depth research and repeated tests on each material and process, and has developed each process in a targeted manner and obtained certification:
1. Remove dirt on the surface of the aluminum shell of the battery cell and particles generated during the laser treatment process

2. The surface roughness of the battery cell is consistent, without sharp burrs, which is convenient for tape adhesion;

3. The appearance of the battery cell surface is consistent, without local yellowing and blackening;

4. The surface tension after treatment is ≥50000dyn/cm, and ≥36000dyn/cm after attenuation for 30min;;5. The cleaning depth of the aluminum shell substrate after three damage depth treatments is ≤10um;

6. The coarse viscosity Ras2 is preferably 0.5~1.6

7 The laser is treated three times in a row, and the temperature rise of the aluminum shell substrate during the treatment process is required to be ≤10°℃;

8. There is no secondary pollution of particles during the laser treatment process.
