Abstract
Continuous tuning of a mode-locked Nd3+ fiber laser over 75 nm is reported. This wide tuning range, which extends over more than twice the FWHM gain bandwidth of Nd:glass, is achieved by optimization of the reflection characteristics and the band-gap energy of the multiple-quantum-well semiconductor saturable absorber. The pulse duration achieved is 300–400 fs over the entire tuning range.
