Abstract
A source of IR-radiation, having an enclosure defining between its walls a sealed-off, electrode-less chamber, the walls having at least one portion transparent to IR-radiation, and the chamber containing a gas mixture of at least one, molecular, IR-active gas, of at least one buffer gas and of at least one noble gas. A method for producing a source of IR-radiation is also described and claimed.
Claims13
A source of IR-radiation comprising;
- an enclosure defining between its walls a sealed-off, electrode-less chamber, said walls having at least one portion transparent to IR-radiation, and said sealed-off, electrode-less chamber containing a gas mixture of at least one molecular IR-active gas, of at least one buffer gas and of at least one noble gas, said source of IR-radiation emitting discrete, solely noncoherent, spontaneous emission frequencies in the IR-spectrum characteristic of the decay of said at least one molecular IR-active gas from its rotational-vibrational state to its ground state.
The source as claimed in claim I wherein said buffer gas is selected from the group containing N.sub.2, CO or a mixture thereof.
The source as claimed in claim I wherein said gas mixture, inside a given volume and configuration of said chamber, provides a total pressure at which the average random propelling time to a wall of said chamber exceeds about 5 milliseconds, for maximizing the radiation output power.
The source as claimed in claim I wherein said gas mixture, inside a given volume and configuration of said chamber, is less than about 5 milliseconds for obtaining faster radiation modulation rate.
