Abstract: A submersible light has an elongated tubular inner housing extending along an axis, an LED strip carrying a plurality of light-emitting diodes fitted into and extending axially inside the inner housing, and an elongated tubular outer housing longer than the inner housing and into which the tubular inner housing fits coaxially leaving end spaces in the outer housing at axially opposite outer ends of the inner and outer housings. Respective bodies of cured potting compound sealing the end spaces at the outer ends of the inner housing.

Abstract: The present invention relates to a method and device for generating optical radiation (18), in particular EUV radiation or soft x-rays, by means of electrically operated discharges. A plasma (15) is ignited in a gaseous medium between at least two electrodes (1, 2), wherein said gaseous medium is produced at least partly from a liquid material (6), which is applied to one or several surface(s) moving in the discharge space and is at least partially evaporated by one or several pulsed energy beam(s) (9). At least two consecutive pulses (16) are applied within a time interval of each electrical discharge onto said surface(s). The delay between and/or the pulse energy of said consecutive pulses is controlled to stabilize the position of an emission center of the plasma (15).

A plasma (15) is ignited in a gaseous medium between at least two electrodes (1, 2), wherein said gaseous medium is produced at least partly from a liquid material (6) which is applied to one or several surface(s) moving in the discharge space and is at least partially evaporated by one or several pulsed energy beams. In the proposed method and device at least two consecutive pulses (9, 18) are applied within a time interval of each electrical discharge onto said surface(s). With this measure, the collectable conversion efficiency is increased compared to the use of only one single energy pulse within each electrical discharge.
