摘要:
A technique for producing a coherent beam of hard X-rays is provided. This technique is based on a short wavelength undulator that uses the fields of an electromagnetic wave to deflect a relativistic electron beam along a sinusoidal trajectory in order to cause it to emit X-rays. The undulator consists of a slow-wave structure that is energized by a second counterpropagating electron beam. Cylindrical and planar structure configurations are provided and also a mechanism for electrical and mechanical tuning to allow control over the wavelength of the emitted X-ray beam.

A radioactive light source consists of a vacuum tight envelope filled with a mixture of a radioactive gas such as tritium with one or more other gases which luminesce when excited by the emission from the radioactive gas without the aid or requirement of any externally applied energy source, such as electrical power. This luminescence may be viewed through the wall of the chamber which may be transparent. Alternatively, all or a part of the luminescence may be converted to a different region of the spectrum by a suitable phosphor layer coated on the wall of the envelope.

In one embodiment of the present invention an oxygen iodine laser includes a gas mixing section. Ground state oxygen and a carrier gas are introduced into the first gas mixing section, sometimes separately. The laser includes a discharge region to generate at least said excited oxygen from the flow of the first gas mixing section. A sensitizer gas having a lower ionization threshold than ground state oxygen is also introduced into the first gas mixing section, such that electrons are more easily produced in the electrical generator. The laser system includes introducing a source of iodine into the excited singlet delta oxygen flow to generate a laser-active gas. In another embodiment a conditioner is placed into the gas mixing section to help mix the flow and/or introduce one or more of the aforementioned gases.

A radioluminescent light source comprising a crystalline III-V or II-VI semiconductor or a group IV quantum semiconductor and a radioactive element adapted to cause the semiconductor to produce light is disclosed. The radioactive element, such as tritium, is either incorporated within the semiconductor, preferably proximate to the p-n junction of the semiconductor, or placed adjacent the semiconductor.

A tapering enhanced stimulated superradiant amplification method and system which utilizes a strongly tapered undulator in reaching significant power outputs and conversion efficiencies. TESSA dramatically increases conversion/amplification efficiencies by violently (sharply) decelerating electrons and taking advantage of produced radiation to further drive interaction toward as it takes advantage of produced radiation to further drive interaction to increase overall radiation output. The system and method configures a strongly tapered undulator to operate in a new mode that is above normal input saturation levels to provide an amplified output with unexpectedly high efficiencies and power.

A method for producing electromagnetic radiation comprising: firing a first laser pulse and generating a plasma region, the first laser pulse penetrating at least partially into the plasma region to create a plasma density wake in the plasma region; providing a group of charged particles in the plasma region arranged so as to be accelerated in the plasma density wake of the first laser pulse; reflecting the first laser pulse after the first laser pulse has penetrated into the plasma region, to give a reflected laser pulse; and arranging the reflected laser pulse to interact with the group of charged particles to generate an electromagnetic radiation.
