Abstract

PURPOSE:To obtain a light source of a long service life with little change in the luminous intensity and the spectrum with the passage of time, by plasma- radiating a sealed gas excited by laser beams in a bulb. CONSTITUTION:Laser beams from a laser radiator 1 are formed into an adequate beam form through optical system members 2 and 3, transmitted through the laser passage, and focused by a focusing optical member 4 to a focus point in a bulb 5. At the focus in the bulb, an electromagnetic field is generated which is strong enough to excite the sealed gas discharged, and a high temperature plasma of the sealed gas generated by a discharge radiates spectra including ultraviolet rays and infrared rays. Since this system has no electrode in the bulb, no change of luminous intensity or spectrum from the evaporation or spattering of the electrode is generated, and a long service life can be obtained.
