摘要： Means are illustrated for electronically exciting phosphor material to provide a source of photon energy for pumping active negative temperature media. Preferably the phosphor has a fast decay time and is so chosen that its emission spectrum substantially matches or coincides with the absorption spectrum of the active negative temperature medium. The source of electrons may be a conventional cathode, or alternatively, one of special construction.

摘要： This invention relates to the field of lasers and in particular to the pump sources used in lasers. Many existing lasers use linear flashlamps in order to create population inversion in the gain medium of the laser. Such pump sources suffer from a number of drawbacks particularly when pumping dye lasers including explosive damage, long optical pulse length and inappropriate spectral emission. This invention provides a pump source for a laser which exploits the surface discharge phenomenon. A dielectric material (1) which is in contract with a gas (9) has electrical energy discharged across its surface in order to provide an electromagnetic emission which is then used to pump the gain medium. By varying the dielectric material or the cover gas used (amongst other variables) the surface emission can be used to pump the laser gain medium.

摘要： A lighting device is provided for emitting superradiant fluorescent light. First material layers are provided which emit predetermined electromagnetic waves of spontaneous emission when supplied with a predetermined energy (e.g. a pumping ray or beam). Second material layers, transparent to the electromagnetic wave, are stacked between the layers of the first material. To provide an improved light emission, the second material layers are arranged so that the interspaces l between the first material layers are smaller than c.multidot..tau..sub.R, where c is the velocity of said electromagnetic wave and .tau..sub.R is a time constant of the spontaneous emission.
