Problem 4 [25 Points] A beam of green light (wavelength 532 nm) is split into two beams, with one beam going straight ahead, and the other diverging at a small angle  relative to the straight-ahead beam. At a distance of 50cm the deflected beam is reflected back so that it meets the straight-ahead ...

Since the measurement errors caused by the vibrations are small, the phase shift due to a plasma less than one fringe would be acceptable. Then the DI is principally free from the fringe jump error by selecting the ...

Nonlinear optics

Nonlinear optics (NLO) is the branch of optics that describes the behavior of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed at very high light intensities (values of the electric field comparable to interatomic electric fields, typically 108 V/m) such as those provided by lasers. Above the Schwinger limit, the vacuum itself is expected to become nonlinear. In nonlinear optics, the superposition principle no longer holds.Nonlinear optics remained unexplored until the discovery of Second harmonic generation shortly after demonstration of the first laser. (Peter Franken et al. at University of Michigan in 1961)
