Abstract: In this work, we propose a method of efficiently generating a watt-level 1.72 µm ultrafast fiber laser by using a Raman amplifier seeded by a single frequency continuous wave (CW) laser. The ...

Abstract: Moving the fiber laser emission to the region below one micron may provide a cheaper, more compact and robust alternatives to the existing solid state lasers. Here, for the first time we ...
