The laser material processing industry demands high throughput while maintaining process stability to achieve optimal manufacturing yield. As output power increases and workpieces grow larger, the need for longer delivery cables rises. However, these longer fibers can trigger Stimulated Raman Scattering (SRS), which negatively impacts laser output power, stability, and reliability. Fortunately, SRS can be effectively mitigated using the Raman Scattering Suppressor (RSS).
indie’s RSS leverages a proprietary chirped tilted fiber Bragg grating (CTFBG) manufacturing process to introduce high losses at the Raman wavelength while maintaining minimal insertion loss at the signal wavelength. This ensures that laser systems can operate at higher powers without sacrificing stability.
indie’s advanced FBG technology offers wide reflection bandwidth and low-loss reflectors, reducing non-linear effects and enabling more efficient, stable lasers. This innovation is critical for improving the performance and reliability of high-power laser systems in demanding industrial applications.
Key Features and Benefits
Enabler:
The RSS allows for the use of longer fibers, essential for modern industrial laser systems.
Increase Power:
Suitable for up to 3 kW oscillators & MOPA up to 5 kW.
Efficient:
Ensures that all photons generated are used for the process.
Value:
Allows to increase the usable output power of fiber laser oscillators by up to 40%.
Increase Reliability:
Enables immunity from back reflections from the work piece.
Partnership:
indie will work through the entire product development process, from prototyping to mass production.
