- Suppression of stimulated Raman scattering employing long period gratings in double-clad fiber amplifiersD Nodop
Institute of Applied Physics, Friedrich Schiller University Jena, Albert Einstein Strasse 15, 07745 Jena, Germany
Opt Lett 35:2982-4. 2010..With only three LPGs inserted into a fiber pulse amplifier, the extractable Raman-free output power was nearly doubled. A numerical simulation of the setup shows good agreement with the experimental results...
- Spectral beam combination of fiber amplified ns-pulses by means of interference filtersO Schmidt
Friedrich Schiller University, Institute of Applied Physics, Albert Einstein Str 15, 07745 Jena, Germany
Opt Express 17:22974-82. 2009..3 mJ of pulse energy are obtained at two different repetition frequencies. A detailed analysis of beam quality as well as the thermal behavior of the combining elements is carried out and reveals mutual dependency...
