Interference and Diffraction02:18

Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.
Confocal Fluorescence Microscopy01:16

Confocal 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,...
Scanning Electron Microscopy01:07

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Phase Contrast and Differential Interference Contrast Microscopy

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...

    Summary

    Optical resonator experiments show that surface irregularities deform beam wavefronts. These imperfections quantitatively transfer power from the fundamental mode to higher-order modes.

    Area of Science:

    • Optics
    • Quantum Optics
    • Laser Physics

    Background:

    • Orthonormal functions describe optical resonator eigenmodes with spherical mirrors.
    • Real-world experiments encounter wavefront deformations due to surface irregularities and internal index inhomogeneities.

    Purpose of the Study:

    • To quantitatively describe power transfer from the fundamental mode to higher-order modes caused by optical component imperfections.

    Main Methods:

    • Theoretical analysis of wavefront deformation effects.
    • Modeling power transfer dynamics in optical resonators.

    Main Results:

    • Irregularities and inhomogeneities lead to a measurable power transfer from the fundamental mode.
    • This power transfer populates higher-order resonator modes.
