Study of Various modes in a Solid State laser
Journal Title: International Journal of Science and Research (IJSR) - Year 2013, Vol 2, Issue 6
Abstract
The light emitted by most lasers contains several discrete optical frequencies, separated from each other by frequency differences, which can be associated with different modes of the optical resonator. It is common practice to distinguish two types of resonator modes“Longitudinal” modes differ from one another only in their oscillation frequency; and “Transverse” modes differ from one another not only in their oscillation frequency, but also in their field distribution in a plane perpendicular to the direction of propagation. Corresponding to a given transverse mode are a number of longitudinal modes which have the same field distribution as the given transverse mode but which differ in frequency.

Quantum Effects in Gravitation
We need to construct a quantum theory which might be well for us to keep in mind whether there would be any observable effects of such a theory. The prediction of the quantum theory of gravitation would be that the force...
