Nanosecond pulse laser generation at 1.55 and 2  μm regions by integrating a piece of newly developed chromium-doped fiber-based saturable absorber

This paper demonstrated the nanosecond pulse laser operation at 1.55 and 2 μm wavelength regions using a newly develop chromium-doped fiber (CrDF) as a saturable absorber (SA) to convert efficiently continuous-wave laser operation to nanosecond pulse laser operation. The laser uses an erbium-doped f...
