Engineers successfully achieved high speed without compromising phase stability. The 1024 x 1024 SLM is incredibly fast with liquid crystal response times ranging from <strong>0.6 to 8 ms<\/strong> (wavelength dependent) for a full wave of modulation when running in typical room temperature environments.<\/p>\n<p>Liquid Crystal on Silicon (LCoS)&nbsp;<a href=\"https:\/\/stagingphotonics.laser2000.co.uk\/product-category\/light-delivery-and-control\/polarisation-phase-control\/spatial-light-modulators-polarisation-phase-control\/\" target=\"_blank\" rel=\"noopener\">Spatial Light Modulators<\/a>&nbsp;(SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with <strong>high refresh rates<\/strong>. This combination provides users with the <strong>fastest response times with high phase stability<\/strong>. The 1024 x 1024 SLM is good for applications requiring high speed, <strong>high diffraction efficiency<\/strong>, <strong>low phase ripple<\/strong> and<strong> high-power lasers<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>High Phase Stability<\/strong> \u2013 Making an LCOS SLM faster usually means the phase stability becomes worse. However, we\u2019ve combined our traditional analog drive scheme with some new proprietary technologies to suppress phase instabilities to an unprecedented 0.2 \u2013 1.0% without compromising the speed. Phase ripple is quantified by measuring the variation in intensity of the 1st order diffracted spot as compared to the mean intensity while writing a blazed phase grating to the SLM.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>High Efficiency Dielectric Mirror Coating&nbsp;<\/strong>&#8211; All the light reflecting off the SLM is modulated \u2013 including the light between the aluminium pixel electrodes. The reflective pixel structure associated with a LCoS SLM backplane acts as an amplitude grating diffracts some light into higher orders. Optically, the active area of the backplane is converted into a flat dielectric mirror by depositing dielectric layers to eliminate the amplitude and optical path variations associated with the underlying aluminium pixel structure. The dielectric stack is kept thin to minimise any drop in electric field across the LC layer. In other words, there are no abrupt changes in phase modulation (such as dead zones) between pixels due to the smoothing which results from separating the LC modulator from the driving electrodes.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Software<\/strong> &#8211; Meadowlark Optics\u2019 SLMs are supplied with a graphical user interface and software development kits that support <strong>LabVIEW<\/strong>, <strong>Matlab<\/strong>, <strong>Python<\/strong>, and <strong>C++<\/strong>. The software allows the user to generate images, to correct aberrations, to calibrate the global and\/or regional optical response over \u2018n\u2019 waves of modulation, to sequence at a user defined frame rate, and to monitor the SLM temperature.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Software Feature<\/strong><\/p>\n<ul>\n<li>Input and Output Triggers<\/li>\n<li>Image Generation<\/li>\n<li>Automated Sequencing<\/li>\n<li>Wavefront Calibration<\/li>\n<li>Global and Regional Look Up Tables<\/li>\n<li>Temperature Monitoring<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Hardware Interface<\/strong> &#8211; The 1024 x 1024 SLM system includes a Gen3 x8 PCIe controller with input and output triggers and low latency image transfers. Triggering can be performed on SLM chip refresh period boundaries of 696 \u00b5s, or even in the middle of refresh periods for applications requiring the SLM be tightly synchronized to external hardware. The controller also includes 752 frames of internal memory that can be loaded in advance, then sequenced at full speed in order to minimise traffic on the PCIe bus during operation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We offer the new of 1024 x 1024 analog spatial light modulators.
