The LCOS-SLM X15213-19 is a product created by Hamamatsu Photonics to meet the growing demand for precision beam-shaping solutions in the 1850-2050 nm spectral range.1
This Liquid Crystal on Silicon Spatial Light Modulator (LCOS-SLM) is designed to fulfill the needs of advanced laser applications, providing unprecedented levels of control and efficiency.
Optimized for Thulium Lasers
The LCOS-SLM X15213-19 was inspired by the growing popularity of Thulium fiber lasers, which are valued for their exceptional beam quality and compact design.
This LCOS-SLM operates within the same spectral window and is designed to work seamlessly with Thulium lasers, making it ideal for applications requiring precision beam shaping.
Applications in Material Processing and Medical Technology
One of the most important applications for the LCOS-SLM X15213-19 is material processing. The ability to actively shape laser beams increases processing efficiency by enabling simultaneous multi-point processing.
This feature has the potential to greatly boost throughput in manufacturing processes. In medical technology, notably in laser surgery, beam shaping provides significant advantages.
For example, its use in ophthalmic surgery with lasers around 1050 nm has improved patient outcomes by increasing laser treatment precision and reducing operating times.
Similarly, Thulium and Holmium lasers used in other surgical procedures can benefit from the LCOS-SLM X15223-19L/R's beam-shaping capabilities.
LCOS-SLM Technical Overview
The LCOS-SLM X15223-19L/R is based on an advanced liquid crystal layer with a 2D array of 1272 × 1024 pixels. Each pixel independently changes the phase of light reflected from its spot by adjusting the orientation of the liquid crystals above it.
As a result, sophisticated 3D beam forms can be generated using digital signals sent to the LCOS-SLM. There are numerous approaches to further tune the device for a certain spectral window.
For instance, high-reflectivity coatings are applied to the target spectral window to improve light-use efficiency and reduce residual heat generated in the LCOS.
The phase retardation caused by liquid crystals for the specified spectral window has been calibrated for the user's convenience, making it an appropriate tool for engineers and researchers working with high-quality laser systems in this sector.
A Step Forward in Beam Shaping Technology
Hamamatsu's LCOS-SLM X15213-19 is a significant development in beam-shaping technology for the 2 µm range. This device expands opportunities in both industrial and medical applications by allowing for greater control over laser beam profiles.
