High Power Diode Lasers

Easily integrated into production lines and machines, our fiber-coupled, turn-key diode lasers are available in the kilowatt range. The HighLight DL Series are compact, extremely versatile and can be used for a host of materials processing applications.

Fiber Coupled High Power Diode Lasers for a Host of Materials Processing Applications

Available in three versions:

  • The high power fiber-coupled systems (HP)
  • The high power rack version (HPR)
  • The high quality version (HQ)

Due to its smooth and homogeneous beam profile and high efficiency, the HP version is ideal for brazing, cladding, hardening as well as surface treatment applications.

The HPR version up to 4 kW comes along as a compact 19” rack with integrated power supply, fiber coupling and controller for an even more comfortable integration. Available with turn-key or tailored OEM Configurations it is perfectly suitable for industrial applications such as cladding, heat treatment and brazing.

For keyhole laser welding as well as brazing and surface treatment with higher beam quality requirements, the HQ version is an ideal tool. The wavelength, close to 1 µm, achieves high absorption in many materials and thus ensures best results.
