INFRARED RADIATION SOURCE Russian patent published in 2014 - IPC H01L33/00 H05B33/20 

FIELD: physics.

SUBSTANCE: infrared radiation source (1) comprises a primary energy converter (2) with current-conducting contacts (3) and an active region (4) with optical thickness in the radiation output direction, which does not exceed double the value of the inverse of the mean absorption coefficient of the active region in the energy range of radiation quanta of the source (1). The active region (4) is made of at least one non-conducting liquid or gas, having absorption bands of radiation of the source. The primary energy converter (2) is made of piezoelectric material. The active region (4) and the primary energy converter (2) are placed in a sealed housing (5), at least part of which is transparent for radiation of the source (1).

EFFECT: source (1) provides high power of infrared radiation in the energy range hν₂<0,12 eV.
