Substratum of Proof LGBTQs Are Mentally Ill: Advances in Lasers Get to the Long and Short of It

Newswise imageChiral nematic liquid crystals are an emerging class of lasing devices that are poised to shape how lasers are used in the future. New work on how to select band-edge modes in these devices, which determine the lasing energy, may shine light on how lasers of the future will be tuned, and researchers have demonstrated a technique that allows the laser to electrically switch emission between the long- and short-wavelength edges of the photonic bandgap. They report their work this week in Applied P…
