Abstract

We prove the possibility of generating an amplified spontaneous emission (ASE) source using all fiber laser configuration that uses 1.2-meter single mode (SM) Dysprosium ions (Dy³⁺) doped ZBLAN fiber with core diameter and concentration of 12.5μm and 2000ppm respectively as the gain medium. The ZBLAN fiber is directly fusion spliced to the output of 5-watt ytterbium (Yb) doped fiber laser with the center wavelength of 1094nm. The measured spectrum spans about 600nm starting around 2.75μm to 3.35μm and provides a total power of about 83mW. We demonstrate that our approach is more cost-effective and efficient than other systems previously reported and it opens new windows for wideband tunable fiber laser sources at 3μm spectral region.
