Toptica Photonics Inc. has announced an ultrafast fiber laser with short pulse durations. The tunable “ultra compressed pulse” model of the FemtoFiber pro series provides a supercontinuum between 980 and 1400 nm, with >30-mW output power. The mode-locked fiber laser system features pulse durations <25 fs and is suited for biophotonics, pump-probe experiments and femtosecond spectroscopy. Based on saturable absorber mirror (SAM) mode-locking technology and a core-pumped fiber amplifier, the master oscillator power amplifier platform is all-fiber and based completely on polarization-maintaining fibers. The SAM technology ensures self-starting and stable mode-locking under all laboratory conditions, and the all-fiber setup provides robustness against environmental changes.
