Toptica's new highly reliable Raman fiber amplifiers are based on patented new technology. With their high power up to 30W the amplifiers cover the wavelength range from 1120 to 1370 nm that is not accessible by Yb or Er fiber amplifiers. With a tuning range of 10nm and a relative intensity noise <1% RMS, TOPTICA offers its own portfolio of RFAs that can be seamlessly integrated with TOPTICA lasers as seeders and frequency converters to reach visible and UV wavelengths.
- 1120 .. 1370 nm , up to 30 W
