The Properties of Undulator Radiation

A new generation of synchrotron radiation light sources covering the VUV, soft x-ray, and hard x-ray speclrai regions is under construction in several countries. These sources are designed specifically to use periodic magnetic undulators and low-emittance electron or positron beams to produce high-brightness near-diffraction-limited synchrotron radiation beams. Some of the novel features of the...

Undulator Radiation in a Waveguide

We propose an analytical approach to characterize undulator radiation near resonance, when the presence of the vacuum-pipe considerably affects radiation properties. This is the case of the far-infrared undulator beamline at the Free-electron LASer (FEL) in Hamburg (FLASH), that will be capable of delivering pulses in the TeraHertz (THz) range. This undulator will allow pump-probe experiments w...

Particle acceleration by stimulated emission of radiation: theory and experiment.

The interaction of electromagnetic radiation with free electrons in the presence of an active medium has some appealing outcomes. Among them is particle acceleration by stimulated emission of radiation (PASER). In its framework, energy stored in an active medium (microscopic cavities) is transferred directly to an e -beam passing through. We have developed a two-dimensional analytic model for t...

[laser-light Amplification by Stimulated Emission of Radiation].

The laser is a new tool which can be a precise and accurate instrument for tissue removal under colposcopic direction in the areas of the cervix, vagina and vulva. Healing is rapid since the laser inflicts minimal tissue destruction. Postoperative pain is minimal and healing is without scar formation. The expense of the equipment and training of the operating surgeon are its only drawbacks.
