Ultrabroad-band Spatial Light phase Modulator

UV-NIR SLM developed by Kyoto Photonics Society allows the phase control of optical pulses with an ultrabroad-band from UV (300nm) to NIR (1100nm).  Effective for the chirp compensation and the pulse shaping of the extreme-short pulse light.

Ultrabroad-band Spatial Light phase Modulator
Feature
  • Our original technique allows the high-optical transparency for the light from the UV to NIR.

  • Only one device can cover the light waves from 300 to 1100 nm.

  • Having the prominent laser tolerance compared to the conventional SLM, the application with the higher-power laser is available.

  • Optical design is simply made because of its optical transparency, and the integration to the existing optical systems is easily made.

  • The external control is available by installing the dedicated software program to the PC.

Ultrabroad-band Spatial Light phase Modulator
Liquid crystal SLM

Liquid crystal SLM is the latest optical device to control the wave surface of the transmitting light (phase-space distribution) by voltage-controlling the liquid crystal placed between two transparent substrate glasses with the transparent electrode.

The optical functions of the conventional optical devices using the lenses and prisms are not alterable because they are employing the solid substances.  On the other hand, freely controlling the liquid crystal, only one SLM device allows a variety of functions.

The control of the polarization and diffraction, the abrasion correction, the compensation of the non-uniform optical phase due to some sort of factors, and the optical pulse shaping intended to generate the ultra-short pulse light and the arbitrary light pulse waveform are available.  This product is the essential key device for the optical-based leading-edge technology.
