Abstract: An exposure device for producing semiconductors and liquid crystals has an optical system capable of effectively using light generated without making a hole in a lamp discharge vessel when high energy laser light is supplied to it for emitting light, such as ultraviolet light. The exposure device has a light source for emitting ultraviolet light, a laser device for emitting laser light, an elliptical reflector for reflecting ultraviolet light emitted from the light source, and an optical system for directing light reflected by the elliptical reflector to an article to be treated via optical elements including a collimator lens and an integrator lens, and a beam splitter having a wavelength selecting ability provided in the optical path for light reflected by the elliptical reflector to allow laser light to be incident on the light source from and opening side of the elliptical reflector.

Abstract: An laser driven light source comprises a bulb that encloses a discharge medium, a laser beam unit for emitting a laser beam, wherein the laser beam is focused in the bulb for generating a discharge, and a beam shield element that is provided in the bulb to shield peripheral devices from the laser beam, which passes through the discharge generated in the bulb.

Abstract: A light source is provided. The light source includes: an elliptical reflection mirror having first and second focal points; a discharge chamber in which a luminescent substance is enclosed and which is disposed on the first focal point; a laser light generator which emits the laser light; and a laser light guide which guides the laser light from an opening side of the elliptical reflection mirror into the discharge chamber. The luminescent substance is excited by providing the laser light to the luminescent substance so as to emit light, and the light is reflected by the elliptical reflection mirror. The laser light guide is disposed in a shade area in which the light reflected by the elliptical reflection mirror is blocked by the discharge chamber.
