Meadowlark Optics’ Liquid Crystal on Silicon (LCoS) Spatial Light Modulators (SLMs) are uniquely designed for pure phase applications and incorporate analog data addressing with high refresh rates (1400 Hz).  This combination provides users with the fastest response times with high phase stability.

High average power handling – The newest SLM from Meadowlark Optics boasts CW power handling of ≥ 1 kW at 1070 nm.  In tests at SPICA, the SLM retained its full >1 wave range of phase modulation at powers up to 1.4 kW. With sapphire coverglass, built-in water cooling, and a suite of calibration tools, the high-power SLM can maintain calibrated performance under extreme laser power loads.

1024 x 1024 Spatial Light Modulator Ultra-High Power

Designed for high power- The Ultra-High Power SLM is designed for performance under high laser power loads.

Active TEC cooling – The UHP SLM includes active thermoelectric cooling to stabilize operating temperature (at lower heat loads) and to combat laser-induced heating at higher temperatures.

Water cooling – The UHP SLM includes a water-cooled copper heat sink with quick-disconnect tubing to connect to an external chiller.

Sapphire coverglass – The high thermal conductivity of the sapphire coverglass allows heat to be directed away from the active area. The SLM housing is designed to thermally contact the coverglass and provide a heat dissipation path into the water-cooled heat sink.

High-temperature liquid crystal – The UHP SLM has a custom liquid crystal formulation that maintains its performance at elevated temperatures, allowing the usable power range of the SLM to be extended.

Real-time temperature reporting – On-chip temperature sensors allow the user to monitor the SLM temperature either through the example program or the software developer kits.

Calibration for high performance at high power – A lookup table calibration kit allows the user to calibrate the SLM at their laser’s wavelength and power level.
