Webb13 jan. 2024 · Another common way to produce MIR light could resort to difference-frequency generation (DFG) between two near-infrared (NIR) beams. Notably, the DFG technique is featured with single-pass configuration, simple light-path alignment and reduced number of optical components, which thus provides desirable advantages like … WebbFar-infrared waves lie in the spectral region between wavelengths of 10 and 2000 pm. Historically these waves have proven particularly difficult to generate, and this has …
