FemtoFiber ultra 1550

Femtosecond fiber laser for quantum communication and terahertz spectroscopy

High-end time-resolved spectroscopy & microscopy experiment in solid-state physics require light engines that are modular and fully-tailored to the application.
TOPTICAs FemtoFiber ultra 1550 provides the basis for a highly modular and customizable system design, offering options for SHG, FHG, supercontinuum generation, and Raman shifting. Based on the master-oscillator power-amplifier (MOPA) approach, the FemtoFiber ultra 1550 can be synchronized to any other laser of the FemtoFiber pro, ultra, vario, and dichro series offering a rich variety of possible laser configurations for your research.
