Performance Under High Laser Power
High Average Power Capability
Tested up to 1.4 kW at SPICA, the SLM maintains its full >1 wave phase modulation range, making it ideal for high-intensity laser environments.
Optimised Thermal Management
The integrated water-cooled copper heat sink features quick-disconnect tubing for seamless connection to external chillers. Combined with active thermoelectric (TEC) cooling, it ensures stable operation across varying heat loads.
Sapphire Coverglass Advantage
The heat-conducting sapphire coverglass efficiently channels heat away from the active area, ensuring high thermal stability and maintaining optical performance at elevated power levels.
Advanced Liquid Crystal Design
High-Temperature Liquid Crystal
The custom liquid crystal formulation sustains reliable phase modulation at elevated temperatures, expanding the usable power range of the SLM.
Real-Time Monitoring
Built-in temperature sensors offer real-time monitoring through provided software tools, enhancing system safety and performance tracking.
Precision Calibration & Control
Lookup Table Calibration
Users can achieve optimal performance by calibrating the SLM at their specific laser wavelength and power level using the included calibration kit.
Analog Phase Modulation
The SLM uses analog data addressing to provide pure analog phase control with high refresh rates (up to 1400 Hz), ensuring fast response and excellent phase stability for demanding optical setups.
