Liquid Crystal Optical Modulators
Liquid crystal modulators feature a broad range of controllable electro-optical properties such as optical activity and birefringence. For this reason, they are excellently suited to achieve a defined modulation setting in terms of amplitude, phase and polarization. Based on the electrical control of the optical properties of a nematic liquid crystal layer, phase, amplitude or the polarization state of a light wave can be controlled.
In a 4f-arrangement or in a cpa-system (chirped pulse amplification) the Liquid Crystal Spatial Light Modulators are excellent tools for modulation of femto second laser pulses in wavelength ranges from 430 nm to 1600 nm.
Custom designs and modifications for specialized applications are possible.
