L³ LIMO Line Lasers® - Line Lasers for Simultaneous Thermal Processing of Large Areas

L³ LIMO line lasers® have been successfully used for optimization of functional layers. The lasers are designed for very Rapid Thermal Processing (vRTP). By means of LIMO's line lasers material properties can be optimized or new material properties can be generated. Even synthesis of new materials is possible.

In comparison to selective processing with laser beam, the treatment with laser line can be done simultaneously. Thereby a higher process velocity is achieved. Furthermore the homogeneous intensity distribution of laser line and the continuous wave mode of the laser enables uniform process results.  


We offer line lasers with the following features:

  • Line length from 1 up to 600 mm
  • Line width from 0.05 mm up to 30 mm
  • Power density up to 600 kW/cm²
  • Inhomogeneity from 10% down to 1%
  • Output power from 30 W up to multikilowatts
  • Wavelength from 790 nm up to 1470 nm
  • Passively cooled package, no microchannels
  • Customized industrial laser system including chiller & power supply and all interfaces needed for the integration into an industrial production environment
