You can use Jenoptik liquid crystal light modulators to control optical characteristics safely and reliably without mechanical moving parts.
Liquid crystal light modulators are excellently suited for modulating the phase, amplitude or polarization state of a light wave. They are based on the electrical control of optical properties of a nematic liquid crystal layer.
An example of the capabilities of our liquid crystal laboratory is the SLM-S spatial light modulator based on a linear array of individually controllable strips. The modulators work for light in the 430to 1600nanometer wavelength range. They are equipped with a single-mask or a dual-mask array. The dual-mask array makes it possible to control the phase and amplitude simultaneously and independently.
Each of the 320 or 640 strips can be controlled separately with 12-bit resolution. All SLM-series liquid crystal modulators are easy to connect to your computer via USB.
On request, we manufacture customer-specific light modulators that are precisely adapted to your individual requirements, including electronics development.

Modulation of Ultrashort Laser Pulses Using SLM-S Liquid Crystal Spatial Light Modulators from Jenoptik
Use the Jenoptik SLM-S liquid crystal light modulators optimally to spatially resolved modulation of phase and/or amplitude of a light beam.
The Jenoptik SLM-S liquid crystal spatial light modulators are variable phase/amplitude masks and make excellent tools for modulating ultrashort laser pulses. You can use them in a 4f arrangement or a CPA system (Chirped Pulse Amplification), for example, as well as to modulate CW laser light.
Jenoptik offers liquid crystal spatial light modulators with single-mask array for phase or amplitude modulation and with dual-mask array for the simultaneous modulation of phase and amplitude. The modulators are available with a resolution of 640 or 320 strips. Each strip can be individually controlled with 12-bit resolution. This means you can configure any strip pattern.
The liquid crystal light modulators are based on the principle of the electrical control of optical properties of a nematic liquid crystal layer (LC layer). You can use light in the 430 to 1600 nanometer wavelength range. On request, we can manufacture customer-specific antireflection coatings for various spectral ranges.
Liquid crystal based light modulators of type SLM are configurated with Ethernet connection.This enables an easy integration of the modulators into a computer network.

Jenoptik SLM in an outclassed performant pulse shaper system for high power Femtosecond Applications
Scientists use Jenoptik-SLM as the center piece of their novel setup for the shaping of femtosecond pulses.
Scientists at the Abbe-Center-of-Photonics of the Friedrich-Schiller-University in Jena have demonstrated a novel setup for the adaptive shaping of femtosecond pulses. The center piece of their setup is the Jenoptik-SLM.
This is the first time that the full potential of the Jenoptik-SLM has been harnessed in an optimized setup of superior performance. They demonstrate highly-efficient self-learning pulse-shaping of 20fs gradients over a time window of picoseconds. For the first time the full area of the SLM can be used, without degrading the beam quality at any wavelength. Using this approach they can shape pulses of multi-gigawatt peak power with a system efficiency of much more than 60%.
