Liquid Crystal Spatial Light Modulators (SLM) – Modulation of ultrashort laser pulses

You can use Jenoptik liquid crystal light modulators to control optical characteristics safely and reliably without mechanical moving parts.

Liquid Crystal Spatial Light Modulator from Jenoptik
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 430 to 1600 nm 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.

Benefits SLM

  • Efficient: Simultaneous modulation of phase and amplitude possible
  • Powerful: Use in the VIS and NIR spectral range
  • Versatile: Use with single- or dual masks
  • Customized: Specific antireflection coatings for your applications
  • Variable: For operating in reflective configuration with easy mountable mirror

Fields of Application

  • Laser and material processing: Pulse shaping of high-power and ultrashort pulse lasers
  • Chemistry: Coherent control
  • Analytics: Multidimensional microscopy and spectroscopy
  • Laser technology: Pulse compression
  • Optics: Simple solutions for modulating light, in particular laser light, in the VIS and NIR range
  • Photonics: Variable phase/amplitude masks are used for shaping of fs laser pulses whenever researching and implementing ultrafast processes

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%.

What is a liquid crystal spatial light modulator?

A liquid crystal light modulator is an electro-optical device that uses liquid crystals to change the intensity, phase, or polarization of an incident light beam. A spatial light modulator (SLM) uses an arrangement of individually controllable pixels to alter a wavefront spatially and temporally. A liquid crystal-based modulator is typically used in various technology fields such as projection, spatial light modulation, and in adaptive optical systems. In principle, an SLM is a variable optical phase and/or amplitude mask.

How does liquid crystal light modulator SLM-Sxxx work?

The liquid crystal cell of an SLM consists of a linear array or a matrix of individual pixels. The Jenoptik modulators SLM-Sxxx utilize the property of electrically controllable birefringence of nematic liquid crystals. By applying a voltage, the molecular orientation of the liquid crystal molecules and thus the refractive index of the liquid crystal layer can be changed individually and with high resolution at each pixel of the SLM mask. Incident light must be linearly polarized.

What is the liquid crystal modulator SLM-Sxxx used for?

The liquid crystal light modulators SLM-Sxxx are used to control phase, amplitude, or polarization of a light beam with high precision and spatially. Both laser pulses and CW light can be modified.

Some SLM applications:

  • SLMs are used in many areas of photonics for fs pulse shaping and characterization. In a 4f setup for shaping ultrashort pulses, for example, the pulse is spectrally split by the first grating of the setup and mapped onto different pixels of the SLM. Here, the light components undergo the desired modulation, after which the pulse is reassembled and has a different shape. Due to the complexity of pulse shaping, self-learning algorithms are often used here.
  • SLMs enable the creation of complex holographic images by controlling the light phase, which supports 3D imaging, holographic displays, and security applications.
  • In modern multimodal microscope technologies, SLMs are used to realize different operating modes. By simply switching the phase pattern imaged on the SLM, almost any spatio-temporal light pattern can be generated without the need to change hardware components.
