TOPTICA presents ultrafast fiber laser with shortest commercially available pulse duration

TOPTICA is presenting a tunable “ultra compressed pulse” (UCP) model of the successful FemtoFiber pro series. The system provides a supercontinuum between 980 – 1400 nm and more than 30 mW output power. It features pulse durations even below 25 fs, the shortest one can get on the market from a modelocked fiber laser system. The system is ideally suited for biophotonics, pump-probe experiments or fs-spectroscopy.

 

After the successful introduction of the FemtoFiber pro IR (at 1560 nm), NIR (second harmonic at 780 nm) and SCIR (supercontinuum from 980 nm to 2200 nm) models in 2009, TOPTICA is now expanding the series with the FemtoFiber pro UCP model. As for all models, the commendation “pro” stands for excellent performance combined with ease of use, reliability and robustness. The FemtoFiber pro UCP is based on reliable saturable absorber mirror (SAM) mode-locking technology and a subsequent core-pumped fiber amplifier. This master oscillator power amplifier (MOPA) platform is all-fiber and based completely on polarization-maintaining fibers. The SAM technology ensures self-starting and a stable mode-locking under all laboratory conditions and the all-fiber setup robustness against environmental changes.

The system includes two motorized prism compressors: the first optimizes the supercontinuum generated by a highly nonlinear fiber. The second motorized prism compressor is used to optimize the pulse duration. Thus pulse durations in the range down to 13 fs can be achieved. The standard repetition rate is 80 MHz, but also 40 MHz is available. Up to three fiber coupled seed ports turn every FemtoFiber pro model into a complex laser system for multi-beam experiments with optically synchronized laser pulses.
