RFA

Our new highly reliable Raman fiber amplifiers (RFA) are based on patented technology. With their high power of up to 30W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fiber amplifiers. For wavelengths outside this range please enquire for a custom system. The RFA is designed using TOPTICA’s high quality engineering excellence and utilizing a stable European & North American supply chain. The all fiber design requires no re-alignment and provides a high degree of stability. The RFA offers a wide tuning range of up to 10nm, a relative intensity noise <1% RMS (10 Hz- 10 MHz) and excellent long term RMS power stability of less than 0.5 % over 100 hours (with a TA pro seed laser).

The RFA is utilising the proven and stable DL pro or TA pro as a seed laser, enabling a seamless integration into the TOPTICA environment of for example wavelength stabilization options. Utilizing a third party seed laser of your choice is possible. Please inquire for requirements.

To reach visible and UV wavelengths the RFA can be integrated with TOPTICA 's SHG & FHG portfolio of frequency doubling and quadrupling systems. With these, high power in the visible wavelengths (for example more than 15W at 589nm) can be achieved while maintaining tunability over the entire RFA tuning range. For UV wavelengths the RFAs can be combined with FHG systems, drawing on TOPTICA’s extensive experience of custom (D)UV systems, while also maintaining the full tunability.

The system consists of two modules:

• The Fiber Pump Module: Providing pump light for the RFA module.
• The Raman Fiber Amplifier Module: High power amplifier module with inputs from the pump module and the seed laser.
