Versatile solutions for a wide range of applications

Directed Energy Lasers and Material processing

In the ranges of 1,060 nm and 2,000 nm, for directed energy lasers and material processing, Exail developed dedicated low frequency phase modulators with matching RF amplifiers for high-power coherent beam combining applications.

The industrial ModBox-CBC is also offered as a proven and robust multi-channels phase modulation solution for multibeam coherent combination. The modulated signals delivered could then be amplified using Exail’s large mode area doped fibers.

Phasing multiple fiber sources of several kilowatt by optical combination can already result in laser architectures delivering powers of up to tens of kilowatts.

Solutions for high-energy laser facilities

High-energy lasers are pulsed lasers with a high output pulse energy. Fiber lasers are known to be the most efficient high-power laser technology demonstrated to date as they leverage extensive industrial development coming from the telecom rise. With its radiation resistant (rad-hard) fibers and its integrated modulation solution based on lithium niobate (ModBox FE) for the temporal shaping, Exail is able to deliver two key components to very powerful laser facilities, for inertial laser fusion or for research on light-matter interactions.

Lasers for biomedical applications

With attractive pricing and low maintenance cost versus YAG lasers, Quasi Continuous-Wave (QCW) fibered lasers are rapidly being adopted by medical field.

Neodynium-doped fiber laser sources can emit near 900 nm to be used as femtoseconds pulsed lasers in medical imaging for the “two-photon microscopy” technique (i.e cellular tissues).

At the other side of the spectrum range, Thulium fiber lasers in the 2 µm range could be used in urology for kidney stone treatment. Whereas 1,550 nm laser could be used for tattoo removal.

Exail components as FBGs laser mirros and doped fibers would be key to provide you high efficiency, high power output and robustness over time.
