Abstract: We characterize a twisted nematic liquid crystal light modulator intended to modulate a laser beam in the mid-infrared spectral region. In particular, to test the device, we employ a CO2 laser operating at 10.6 mum. We analyse the optical characteristics and the response times of the modulator and consider the possibility of using it as a single element of a multiple-layered liquid crystal device.
