Patent ID: 7095163

Claim:
A method for the production of a visible, UV, or IR radiation ( 9 ), within a spectral or wide band wavelength range, either pulsed or continuous, comprising the steps of: creating at least one first chamber ( 3 ) closed by an external wall ( 2 ) with a substantially transparent material in which a material ( 4 ) is disposed capable of being excited by means of microwaves irradiation, said at least one chamber ( 3 ) having an internal wall ( 1 ) that defines at least one second chamber ( 5 ) separated from the at least one first chamber and accessible from the outside; introducing in said at least one second chamber ( 5 ) at least one source ( 6 ) of microwave radiation ( 8 ), and exciting said at least one source ( 6 ) according to a predetermined function of power and frequency, said at least one source ( 6 ) emitting a radiation ( 8 ) with subsequent excitation of said material in said at least one first chamber ( 3 ).
