Abstract: A source of microwave energy (11) is connected to a waveguide (14) having a slot (16) along one wall (17) thereof. A nominally cylindrical cavity (18) enclosing an electrodeless lamp (21) is closed at one end and coupled at a second end to the slot (16). The nominally cylindrical cavity (18) has a non-cylindrical surface portion (26) which increases coupling from the slot (16) to a second resonant mode which is orthogonal to a first primary resonant mode, creating a high amplitude standing wave in the region of the electrodeless lamp. Once ignition of the lamp occurs, the impedance of the lamp decreases significantly, and most of the microwave power for sustaining illumination is coupled to the electrodeless lamp in the first resonant mode producing a substantially matched load to the microwave source (11).

Abstract: An electrodeless lamp includes a stationary bulb (10) containing a fill for producing a discharge, the fill has a primary radiating material which ordinarily produces an unstable discharge in the absence of bulb rotation. The fill further includes an alkali metal in an amount sufficient to stabilize the discharge without bulb rotation. The alkali metal may be, for example, cesium bromide. Preferably, the fill is excited by a non-stationary electric field (E, E1) such as, for example, a circular polarized electric field.
