Free Electron Laser patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.

04/26/07 - 20070091939 - Microscope and lamphouse
A microscope includes an illuminating unit that includes an excitation light source emitting an excitation light, and a phosphor receiving the excitation light and emitting illumination light in a specific wavelength range. The illuminating unit illuminates a specimen with the illumination light. The microscope also includes an observation unit for ...

09/28/06 - 20060215712 - Method and arrangement for the efficient generation of short-wavelength radiation based on a laser-generated plasma
The invention is directed to a method and an arrangement for the efficient generation of intensive short-wavelength radiation based on a plasma. The object of the invention is to find a novel possibility for the generation of intensive short-wavelength electromagnetic radiation, particularly EUV radiation, which permits the excitation of a ...

03/23/06 - 20060062258 - Smith-purcell free electron laser and method of operating same
A free electron laser for generating a Smith-Purcell radiation. In one embodiment, the free electron laser includes a grating having a grating surface, an electron emitter for generating a beam of electrons, and a guiding member positioned therebetween the electron emitter and the grating for directing the beam of electrons ...

02/23/06 - 20060039417 - Compact system and method for the production of long-wavelength, electromagnetic radiation extending over the terahertz regime
A compact system and method are provided for implementing the generation of electromagnetic radiation extending over mm-wavelength to sub-mm-wavelength or terahertz range. The generated electromagnetic radiation can be broadband or have a variable bandwidth. Electrons are accelerated to a chosen energy and undergo subsequent or simultaneous temporal or spatial compression. ...

08/11/05 - 20050175042 - Method for enabling high-brightness, narrow-band orbital radiation to be utilized simultaneously on a plurality of beam lines
In an electron accelerator such as an electron storage ring, a linac or an energy-recovery linac, accelerated electron bunches are subjected to light-electron interaction to have a varying profile of electron density and the thus modulated electron bunches are passed between deflecting magnets or injected into an undulator to generate ...

06/23/05 - 20050135437 - Bessel free electron laser device
Methods and apparatus are provided for modifying a free electron laser (FEL) to produce a non-diverging laser beam. A relativistic electron beam is converted to a Bessel beam in an FEL resonator with conical end mirrors, and the Bessel beam is coupled to the optical field within the laser resonator. ...
