A portable laser system fills the terahertz gap
"Electrons trapped in a series of potential wells emit light with a hard-to-produce terahertz frequency without the usual need for cryogenic cooling."

Focus: Green Light for Terahertz Movies
"A new technique uses long-wavelength infrared radiation to produce video with a high frame rate, which could be useful for nondestructive testing of productssdf.Researchers generated video at 3000 frames per second using so-called terahertz radiation, waves at the long-wavelength..."
