RFA

• Up to 30 W output power
• 1120–1370 nm wavelength range
• Up to 10 nm tuning range
• Single-frequency, CW operation
• All-fiber design—stable and maintenance-free
• Low-intensity noise: <1% RMS
• Long-term power stability: <0.5% RMS over 100 hours with TA pro seed laser
• Compatible with DL pro / TA pro seed lasers

Our highly reliable Raman fiber amplifiers (RFA) are based on patented technology. With a high power of up to 30 W, the amplifiers cover the wavelength range from 1120 to 1370 nm, which is not accessible by Yb or Er fiber amplifiers. 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 realignment and provides a high degree of stability. The RFA offers a wide tuning range of up to 10 nm, 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 utilizes the proven and stable DL pro or TA pro as a seed laser, enabling seamless integration into the TOPTICA environment of, for example wavelength stabilization options.

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
