Liquid Crystal Spatial Light Modulator Matrix
(MIIPS) is a technique based on the computer-controlled phase scan of a linear-array spatial light modulator. Through the phase scan to an ultrashort pulse, MIIPS can not only characterize but also manipulate the ultrashort pulse to get the needed pulse shape at target spot (such as for optimized peak power, and other specific pulse shapes). The core technology that has advanced this field is the liquid crystal spatial light modulator (SLM), allowing high resolution tailoring of light in amplitude, phase, polarization, or even more exotic degrees of freedom such as path, orbital angular momentum, and even. Spatial light modulators, as dynamic flat-panel optical devices, have witnessed rapid development over the past two decades, concomitant with the advancements in micro- and opto-electronic integration technology. Liquid crystals are birefringent, so applying a voltage to the cell changes the effective refractive index seen by the incident wave, and thus the phase retardation of the reflected wave. Spatial Light Modulators SLM-S320(d) / 640(d) are linear array SLMs based on nematic liquid crystals and are proven tools for modulation of ultrashort laser pulses in the wavelength range 430-1600 nm. Tointegrate a switching device on the glass substrate, we designed a high-performance oxide thin-film transistor with a mini- mum channel length of 1 m and a maximum processing temperature of 380°C.
