Abstract
A high intensity source produces light energy output principally in the 3A to 4300A spectral region. An envelope of material substantially transparent to light energy within the desired spectral region is sealed to contain xenon gas in an amount sufficient to produce at least one atmosphere of pressure in its unheated state and also mercury in an amount sufficient to develop a vapor pressure of not less than one atmosphere when the envelope is heated to an operative temperature. Electrically conductive electrodes communicate with the interior of the sealed envelope forming a gap therebetween which becomes a conductive arc upon connection of external terminals of the electrodes to a source of pulsed electrical power. The sealed envelope and its contents are maintained at an operative temperature of the order of not less than approximately 500.degree. C, ensuring the vapor pressures required to produce the high intensity output within the desired spectral region.
