Paper Abstract

We have demonstrated a Tm-Ho-codoped silica fiber laser pumepd by a third-stokes Raman Fiber Laser (RFL) at 1212 nm. RFL consists of Yb-double clad fiber laser (DCFL) as a pump, 1-km Single mode fiber (SMF) and cascated cavities made with fiber Bragg gratings (FBG). For the 30-cm-long Tm-Ho-codoped silica fiber, the output power of 400 mW is obtained at wavelength of 1790 nm (due to the laser radiations of Tm3+ ions). The optical-optical conversion efficiency and the slope efficiency are 18% and 23%, respectively. For the 270-cm-long Tm-Ho-codoped silica fiber, the output power of 450 mW is obtained at 1970 nm; this is the laser emission from Ho3+ ions. The optical efficiency is 18% and the slope efficiency is measured to be 31%. This is the highest output power ever reported for a Tm-Ho-codoped silica fiber laser.
