„In my eyes, the FemtoFiber ASOPS laser solution from TOPTICA is the best possible laser system for our research on spin dynamics with highest sensitivity. By combining the flexibility and stability of the fiber lasers with the pump-probe detection speed of the ASOPS electronics, we can perform cutting-edge research that was previously not possible like the recent detection of magnon polarons.”
Prof. Manfred Bayer, TU Dortmund, Germany
FemtoFiber ASOPS
Advanced laser system for ultrafast pump-probe spectroscopy with kHz scanning rates
- All electronic pump-probe delay with <100 fs timing jitter
- Compatible with all fiber lasers from TOPTICA
- Flexible scanning window up to 100 ns using pulse picking
- Degenerate pump-probe spectroscopy
- Extremely stable, compact, flexible, and turn-key
FemtoFiber ASOPS is a true game changer for ultrafast pump-probe spectroscopy! The unique combination of TOPTICAs fiber laser technology and the high-end ASOPS electronics from Laser Quantum, really pushes the limits in terms of detection speed and sensitivity. TheASOPS engine serves as a seeder for our entire fiber laser portfolio, which allows you to select the perfect laser combination for your ultrafast applications. The all-fiber design makes this advanced laser solution truly turn-key and easy-to-use, allowing you to focus on thing that matter - your research!
