Abstract:
A phase-conjugate mirror based on stimulated Brillouin scattering in gaseous SF(6) at 248 nm was used for pattern transfer. We measured the pressure dependence of backscattering efficiency of the Brillouin mirror, which approached 40% reflectivity and was limited by the onset of gas breakdown. Measurement of the image contrast ratio showed high statistical fluctuation due to the threshold behavior of Brillouin scattering.

Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

01:16Confocal Fluorescence Microscopy
Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...
