BaMgF4 | Infrared Crystal is one of the most useful materials in UV applications. It has advantages of good stability, high beam-quality, and it can also be continuously adjustable in the UV and VUV. Its short UV cut-off wavelength (125nm) makes it applicable to the quasi phase matching (QPM) in vacuum UV lasers. In addition, it is now widely used in high-resolution rate spectroscopy, micro nano-processing decomposition, UV lithography, and medicine categories.
