Femtosecond neodymium-doped fiber laser operating in the 894- to 909-nm spectral range

We demonstrate a practical ultra-fast Nd-doped fiber laser operating in the 894-909 nm spectral range, in both soliton and stretched pulse dispersion supporting regimes. Using purposely designed semiconductor saturable absorbers, a truly self-started mode-locking regime of operation with clean, transform limited pulses, was achieved.
