- Page 6 When a repeating, linear phase pattern is displayed on the SLM, it will function similarly to a blazed diffraction grating. The diffraction efficiency is the power in the first-order of the diffraction pattern divided by the zero-order when the phase of the SLM is set to zero across the panel. These measurements were made at 633 nm, 1064 nm, or 1550 nm for several test patterns with varying phase steps, effectively creating gratings with varying line spacing (denoted as line pair / mm).

- Page 9 ® shift. Thorlabs' Exulus 2D SLM is fabricated with liquid crystal on silicon (LCoS) technology, which is based on display technology. This allows it to provide far more pixels than lower-order phase modulators such as segmented or deformable mirrors. Also, the phase shift of one pixel has little crosstalk with other pixels.
- Page 10 ® The main component of the Exulus is the 2D SLM LCoS panel. Figure 1 shows a basic schematic of the LCoS panel. The liquid crystal layer is sandwiched between the top transparent and conductive ITO electrode, and the reflective electrode on the bottom. Each pixel on the SLM panel corresponds to individually addressable electrodes on the bottom.
- Page 11 Effects of Focusing and Tilt Due to the fill factor of the SLM panel, there is a small gap between the pixels. This in turn causes higher diffraction orders and a high-energy zero-order spot which is unaffected by the SLM, but inherently exists at the output. The center bright spot often overlaps with the holographic projection on the same image plane, as is visible in Figure 4.

Page 13: Testing Method
Testing Method Thorlabs' LIDT testing is done in compliance with ISO/DIS 11254 and ISO 21254 specifications. First, a low-power/energy beam is directed to the optic under test. The optic is exposed in 10 locations to this laser beam for 30 seconds (CW) or for a number of pulses (pulse repetition frequency specified). - Page 14 Thorlabs expresses LIDT for CW lasers as a linear power density measured in W/cm. In this regime, the LIDT given as a linear power density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size, as demonstrated by the graph to the right.
