FX series

The family of the FX series lasers is completely solid-state femtosecond lasers with high average power, exceptional pulse energy and excellent stability.

Yb-doped KYW crystals used in these lasers allow being pumped directly by a diode eliminating the necessity in an intermediary pump laser used in traditional Ti:Sapphire lasers. For this reason the FX series lasers to the full extent combine compactness and reliability of fiber systems with advantages of solid-state technologies.

The FX100 and FX200 air cooled diode-pumped lasers have been developed specially for long-term and stable operation with minimum of service. The lasers are built on the turn-key principle and can be operated by a user not experienced in working with laser equipment.

Unpretentiousness of the FX series lasers is conditioned by the rigid dustproof design with thermal stabilisation of all the critical cavity components. Supplement these features with service intervals of more than 10 000 hours and obtain a device which will be duly appreciated by industrial users.

Excellent beam quality will satisfy the most demanding requirements of scientists performing fine experiments. Thanks to the SESAM® technology you will daily save your time due to self-start of the femtosecond mode immediately after switching on the laser and will be sure in the precision of your experiments thanks to ideal long-term stability of the laser output parameters.

If you need to use the laser you already have in your laboratory for applications requiring VIS or UV femtosecond radiation, it can be supplemented with the SHG (518nm), THG (345nm) or FHG (259nm).
