Anomalous linewidth behaviour in short cavity single frequency fiber lasers

Anomalous linewidth behaviour in short cavity single frequency fiber lasers
An experimental investigation of the anomalous linewidth behavior in a DFB fiber laser is presented. It is found that not only does the linewidth deviate from the Schawlow-Townes linewidth formula by increasing with pump and laser power, but it also varies significantly with the pumping configuration. These observations have potentially important implications for the design and operation of such fiber lasers, which suggest that designs for maximizing the output power and efficiency in these fiber lasers likely need to take into account trade-offs in their single frequency characteristics.

Abstract

An experimental investigation of the anomalous linewidth behavior in a DFB fiber laser is presented. It is found that not only does the linewidth deviate from the Schawlow-Townes linewidth formula by increasing with pump and laser power, but it also varies significantly with the pumping configuration. These observations have potentially important implications for the design and operation of such fiber lasers, which suggest that designs for maximizing the output power and efficiency in these fiber lasers likely need to take into account trade-offs in their single frequency characteristics.
