Description

FemtoLux 3 is a modern industrial femtosecond laser aimed for micromachining, engraving and ophthalmologic surgery applications. Laser delivers up to 3 W of average power and up to 2 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 programed up to 5 ps.
