In various R&D projects, Fraunhofer ILT is developing and building lasers with output powers in the kilowatt range. By using fiber Bragg gratings and pump light couplers, it can develop fully fiber-integrated and, thus, particularly robust fiber lasers as resonators or amplifiers. The wavelength, pulse duration and polarization of the light can be adjusted to suit the application.
In cooperation with our customers we design and conceptualize adapted beam sources for various applications, such as:
- Ytterbium-doped fiber lasers (1000–1100 nm)
- with up to 1 kW output power, linearly polarized, in single-mode operation
- with up to 100 kW peak power, pulse duration range from pico- to microseconds
- with up to 250 kW peak power, Q-switched, multi-mode fiber
- Thulium-doped fiber lasers (1900–2000 nm)
- with up to multi-100 W peak power, QCW from μs to ms, in single-mode or multi-mode operation
- with up to multi-10 W output power, in single-mode operation
- Holmium-doped fiber lasers (2000–2100 nm)
- with up to 10 W output power, linearly polarized, in single-mode operation
Applications include (industrial) structuring of surfaces with pulsed radiation, adhesive surface preparation of composite components, medical technology, or cutting and welding.
