The Ultrafast Watt Pilot is intended for laser pulses of <100 fs. It incorporates a motor-driven rotating Achromatic λ/2 phase waveplate and two high-performance Broadband 72° Thin Film Polarizers that separate s-polarized and p-polarized beams in parallel directions. The intensity ratio of the separated beams is continuously tuned by rotating the waveplate.

There are 2 standardized types of ultrafast attenuators – one for maximum transmitted energy and one for maximum blocked beam.

The Watt Pilot is essential in systems in which stable adjustments to laser power are necessary. Despite the stand-alone device look, the motorized attenuator is compact and can be easily integrated into custom optical systems.

Custom wavelengths are available upon request.

Contact us and we will find a solution for your beam attenuation, power control, beam splitting needs. We can also recommend compatible optical components for your beam delivery applications.
