Maximum laser power on the Spatial Light Modulator thanks to optimized beam shaping
In many laser-based applications, targeted light distribution is crucial for efficiency, process stability and quality. Display systems such as Spatial Light Modulators (SLMs) enable flexible adjustment of the beam profiles. However, if these are illuminated with the typical Gaussian beam profiles, this results in inhomogeneous and locally limited illumination of the displays, which means that the laser power can often only be used to a limited extent.
An upstream top-hat beam shaper ensures a homogeneous distribution of the laser power over the entire active surface of the display, allowing the maximum laser power to be used and improving the image quality.
The GTH beam shapers from TOPAG can be flexibly adapted to different target sizes and enable homogeneous illumination of the typically rectangular displays with top hat profiles in the millimeter range. They can be used for a wide wavelength range of 200-1200 nm and high average powers down to the femtosecond range. In combination with adapted collimation optics, ideal starting conditions are created for the best possible illumination of the displays.
