1400W damage threshold (LIDT) sapphire pure phase spatial light modulator
Product Introduction:
The sapphire pure phase spatial light modulator (SLM) launched by Meadowlark Optics has a continuous wave optical power tolerance of ≥ 1400W at a wavelength of 1070 nm. In SPICA testing, the SLM was able to maintain a complete phase modulation range of over 1 λ (2 π) even at a power of up to 1.4 kW. With its sapphire cover glass, built-in water cooling device, and a set of calibration tools, this high-power spatial light modulator can maintain the temperature of the liquid crystal and maintain good phase modulation linearity even under laser power load.
Meadowlark Optics' award-winning analog addressed pure phase spatial light modulator (SLM) provides precise delay controlled phase or amplitude requirements for spatial light modulation. Our SLM is composed of liquid crystal (LC) pixels, each of which is independently addressed as an independent variable retarder. These SLM can be easily integrated into variable input/output devices that require programmable masks and optical systems. Applications include correlation, spectroscopy, data storage, ultrafast pulse shaping, optics, active optics, and adaptive optics calculations, beam steering, and wavefront correction.
The basic structure and operation of SLM are similar to our standard LC variable retarder. ITO transparent conductors are etched into individual electrodes to form independent and controllable pixels. Max pixel spacing and fill rate are crucial for optimizing performance and resolution. The proprietary design and technology enable Meadowlark Optics to provide tight pixel spacing. You can customize pixel configuration.
Space light phase control or modulation is achieved without changing the intensity distribution of the incident beam. The linearly polarized light parallel to the special axis of the LC material is phase modulated by the voltage applied to each pixel. The optical path difference between adjacent pixels can be adjusted to a full wavelength (2 π) or a delay amount required by the customer (e.g. 2 π -6 π).
