Design of an electron microscope phase plate using a focused continuous-wave laser

We propose a Zernike phase contrast electron microscope that uses an intense laser focus to convert a phase image into a visible image. We present the relativistic quantum theory of the phase shift caused by the laser-electron-interaction, study resonant cavities for enhancing the laser intensity, and discuss applications in biology, soft materials science, and atomic and molecular physics.Comment: 5 pages, 3 figure

Obtaining of prescribed-profile beams from a laser with stable (unstable) resonator and graded reflectance mirror

The standard approach to developing new laser resonators with graded reflectance mirrors is based on solving the direct problem of finding the resonator fields for given mirror reflectance function.1 As a result the output beam profiles and intracavity fields do not generally meet the application needs.</jats:p
