07 Jul 2016 LASER COMPONENTS offers phase modulators for use around 800nm. The NIR-MPX800 modulators from the Photline range, manufactured by iXBlue Photonics, use a proton exchange based waveguide process that gives them unparalleled stability and a high photorefractive damage threshold.
The NIR-MPX800 range of modulators includes modulators for 5GHz, 10GHz and a model specifically designed for low frequency modulation. Applications include interferometric based sensors, Pound-Drever-Hall laser frequency locking and optical sideband generation.
There are also Photline intensity modulators for 800nm as well as both types of modulator for use at wavelengths around 1000nm, 1310nm, 1550nm and 2µm.
