Abstract
The absorption spectrum of the Yb3+-doped photonic crystal fiber covers from 770â¯nm to 980â¯nm. A less flatness broadband continuous spectrum and a short peak are generated in the uniform Yb3+-doped photonic crystal fiber. Supercontinuum from 388â¯nm to 1590â¯nm is received in the tapered Yb3+-doped photonic crystal fiber, which covers almost two octaves, generating an ultra flat (7â¯dB) continuous spectrum coming from 926â¯nm to 1554â¯nm in the long waveband, and receiving a 62â¯nm width, high and violet peak from 388â¯nm to 450â¯nm in the purple waveband by femtosecond pulse. The up conversion efficiency of pump power in tapered Yb3+-doped photonic crystal fiber is up to 59.4%, while the uniform is only 6.3%.
