Description

FemtoLux 3 is a modern femtosecond fiber laser aimed for both R&D use and industrial integration. Laser delivers up to 3 W of average power and up to 3 μJ femtosecond pulse energy. FemtoLux 3 is a flexible platform which allows to optimize output parameters for the desired process. The repetition rate as well as the output power can be easily changed with integrated pulse picker.

With burst mode enabled FemtoLux 3 can generate bursts of pulses with energy above 10 μJ with burst shape controlled in real time via analog input. Pulse duration can also be tuned from 300 fs up to 5 ps. Having laser control application running on a wireless tablet, makes FemtoLux series
lasers a most technologically advanced and user friendly as never before for any type of user, be it researcher or industrial user.
