Lasers
Exail masters design and manufacturing of all the key components of a fiber laser: from optical fibers and doped fibers, to LiNbO3 modulators and their matching electronic components.
The company has also developed integrated laser solutions such as: micro-optics assemblies to turn lab size experiments into compact systems, the ModBox as an integrated modulation solution for high-energy laser, and a narrow-linewidth laser system for the manipulation of quantum systems (such as cold atoms).
Mastering the full value chain of fiber lasers key components
Leveraging unique vertical integration capabilities, Exail offers a complete range of state-of-the-art and reliable optical components perfectly suited to the development of high-performance laser systems.
Exail's large portfolio is dedicated to fiber lasers from 300 nm to 2200 nm, for CW and pulsed lasers. It includes components for the fiber laser cavity part, for the optical fiber amplifier part, or for the anti-Brillouin part.

Pushing the frontiers of 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 state-of-the-art modulation solutions based on lithium niobate (ModBox FE) for the temporal shaping, Exail delivers two key components to very powerful laser facilities (i.e LLNL NIF, US). They contribute to reaching new limits in terms of performance in inertial laser fusion and light-matter interactions, for example.
Enhancing Directed Energy Lasers and Material processing
Exail is a world leader in the manufacturing of low frequency phase modulators and their matching RF amplifiers, for high-power fiber lasers, in 1 and 2 µm ranges. They are used in laser architectures that can deliver tens of kilowatts, for Directed Energy Lasers (DEL) and material processing applications. This is done by phasing multiple fiber sources by spectral beam combination (SBC) or coherent beam combination (CBC).
Exail also offers an integrated multi-channel phase modulation solution for multibeam coherent combination, the ModBox-CBC, as well as a range of doped optical fibers and Fiber Bragg Gratings fitted for high-power lasers systems.


Powering lasers for biomedical applications
With attractive pricing and low maintenance cost versus YAG lasers, Quasi Continuous-Wave (QCW) fibered lasers are rapidly being adopted in the medical field. Exail optical components such as FBGs laser mirrors and doped fibers provide high-efficiency, high-power output and robustness over time.
Laser sources based on Exail neodymium-doped fiber, that emits near 900 nm, is an unrivaled technology in medical imaging (i.e cellular tissues). They are used as femtosecond pulsed lasers with the “two-photon microscopy” technique. Exail has the only commercial solution currently available for this application. At the other side of the spectrum range, thulium fiber lasers in the 2 µm range can be used in urology for kidney stone treatment. Finally, Exail fibers in the 1,550 nm range are adapted for the assembly of laser sources for tattoo removal.
Pulsed Lasers for LIDAR
Whatever the application (autonomous driving, wind LIDAR, telemetry, gaz monitoring, ...), Exail has developed key components that help to increase the performances of LIDAR systems.
With its extensive know-how in designing and manufacturing optical fibers, Exail can deliver a large variety of doped and passive fibers for laser cavity and amplifiers dedicated to the assembly of LIDAR laser sources. Exail amplitude and phase LiNbO3 modulators are other key components to improve the pulse pattern shape, to increase range and definition of LIDAR systems. Finally, Exail customized micro-optical benches can be useful on the reception side, whether the LIDAR systems rely on “time-of-flight” measurement with scan capability (distance measurement) or is dedicated to measure wind speed.

The Pound-Drever-Hall (PDH) technique for stabilizing lasers
One of the most powerful active laser stabilization techniques is the Pound-Drever-Hall technique, where the emission frequency of the laser light is locked to the resonance of a stable, high finesse cavity.
Exail has developed a comprehensive series of optimized electro-optic phase modulators for implementing this PHD technique. Here is a guide to help you choose the right modulator:
