Multi-wavelength laser systems

System with 1064 nm, 532 nm, and 355 nm beams in a single unit.Spot diameter and focal position are individually adjustable for each wavelength via dedicated zoom beam expanders. Computer-controlled beam expanders are available as an option.

Versatile Multi-Wavelength Laser Systems for Selective Material Processing

We provide advanced laser systems that combine multiple wavelengths—1064 nm, 532 nm, and 355 nm—in a single, integrated solution. This enables precise, material-selective layer processing within one setup.

For example:

  • 532 nm effectively removes semiconductor materials from transparent electrodes.

  • 355 nm can ablate transparent electrodes from glass substrates.

  • 1064 nm allows for the removal of metal electrodes from semiconductor layers.

The desired wavelength can be selected via computer control, allowing flexible, automated processing of different material layers in a single workflow.

Every circle indicates an available laser with fixed pulse duration. Every line indicates a laser with variable pulse duration with range of pulse diration

Applications (examples)

And Laser scribing (P1, P2, P3 and insulation cut) for interconnection of thin-film solar cells to modules. We use a "trough-the-lens" positioning system with special Illumination for positioning the P2 and p3 scribe with up to ±  5 µm in relation to the P1 scribe
Laser edge deletion (LED) together with the laser scriber in one system or as a cost effective separate system.
