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, polarization and spectrum.  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 SLM-S640/320 and SLM-S640d/320d are excellent tools for modulation of femto second laser pulses in wavelength ranges from 430 nm to 1600 nm.

The modulators are available with a resolution of 640 or 320 stripes as single or double masks for modulation of phase and/or amplitude.

Custom designs and modifications for specialized applications are possible.

Integrated Optical Amplitude and Phase Light Modulators

Both the Integrated Optical Amplitude Modulator and Phase Modulator are compact fiber-coupled electro-optical light-modulators. Providing fast electro-optic response, both allow for modulation frequencies as high as the Gigahertz range.

Available modulators can handle wavelengths in the visible and the infrared spectrum.

Applications:

• Analog modulation with high dynamics
• Digital modulation
• Short laser pulse generation
• Photo finishing
• Laser scanning microscopy
• Interferometric metrology
