Abstract

The possibilities and conditions of high spatial frequencies transition are evaluated in the present work for the photothermic spatial light modulators (SLMs) in which the recording is carried out to the peritectic semiconductor compositions such as thallium telluride under the action of laser irradiation short pulses. Such photothermic SLMs may store recording at room temperature which is a distinguishing peculiarity this SLM among the others realizing recording due to the phase transition of the second of the second kind. It shown that high resolving power is achieved with short pulses, and optical recording is performed both at expense of the absorption variation and at expense of variation of the recording medium films polarization properties.
