Infrared Laser

The infrared Laser type CL100 fabricated by CleanLaser is mainly marketed for cleaning procedures. In the industrial sector, the laser is preferably utilized for decoating, de-painting and cleaning works. Furthermore, it is partially suitable for structuring and labeling.
The operating principle is based on the evaporation of dirt and/or top layers by the focused laser beam. At appropriate process parameters, the high power but simultaneously short laser pulses cause only a very low thermal load on the base material.

In addition to the known ones, INNOVENT is investigating the following fields of application:
- Laser based silicatization
- Chemical surface modification of non-laser-sensitive polymers

Device Configuration
Laser type: diode-pumped solid state laser
Wavelength:1064 nm
Power:5 - 100 W
Pulse frequency:50 - 200 kHz
Maximum pulse energy:1 mJ
Focus diameter: 55 - 130 µm
Beam profile:Gaussian / Top Hat
Working field size: max. 280 × 280 mm
Scan speed:  50 - 3000 mm/s


Due to the computer-controlled 2D scanning head, a high spatial resolution can be realized. Depending on the selected objective, the resolution is in the range of the focus diameter. The smallest possible image is a dot of about 55 µm. All geometric images respectively structures are created by combining single pixels.
