List of optical topics

	Nonlinear optics - Wikipedia, the free encyclopedia
		Nonlinear optics is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the polarization P responds nonlinearly to the electric field E of the light.
		This nonlinearity is typically only observed at very high light intensities such as provided by pulsed lasers.
		In the language of nonlinear optics, the interacting beams result in a nonlinear polarization within the material, which coherently radiates to form the phase-conjugate wave.

	Photonics Research Group
		Nonlinear optics has numerous applications in communications and optical computing, as nonlinear material effects allow for the design of switches, couplers, modulators, and all-optical signal processing systems.
		Nonlinear optics also has a number of inherent benefits, such as the ability to compensate for dispersion and diffraction effects, as evidenced by temporal and spatial solitons.
		The development of a suitable simulation tool for nonlinear optics is crucial if such effects and their applications are ever to be studied.

	MATERIALS SCIENCE: DISORDERED MATERIALS AND NONLINEAR OPTICS
		Lasers are capable of generating external fields of sufficient intensity for nonlinearity to occur, and the field of nonlinear optics has developed largely as a result of the invention of the laser.
		In general, in nonlinear optics, the induced electric polarization of the medium is not a linear function of the strength of the external electromagnetic radiation, which leads to phenomena more complicated than phenomena occurring in linear optics.
		In the 1990s, a new class of synthetic nonlinear optical multilayer structures was developed and commercialized that efficiently converted still weaker, fixed-frequency beams from small solid-state lasers to tunable visible and infrared radiation for applications in materials processing, remote sensing of environmentally sensitive gases, and interferometry (3).

	Nonlinear optics of periodic and quasiperiodic structures (Site not responding. Last check: 2007-11-07)
		Till recent times most of the development in nonlinear optics of periodic and quasiperiodic media has been in the theory front, largely due to the lack of proper and comparatively cheap fabrication techniques.
		For a defocusing nonlinearity the gap shifts to the lower wavelengths because of decrease in the average refractive index, and at the same time a broadening of the gap occurs due to an increase in the refractive index contrast (assuming the nonlinear layers having lower index).

	Valerio Lucarini - Nonlinear Optics
		My goal was discussing if in nonlinear optics it was possible to explicitely derive properties of the nonlinear susceptibilities such as Kramers-Kroenig relations and sum rules, which in linear Optics have played such a great role, having proved to be fundamental tools both in fundamental and applied research.
		This team has probably contributed the most to the theory of Nonlinear Kramers-Kroenig relations and sum rules by improving the general theoretical results, by introducing algorithms to perform the calculations in both conceptual and more realistic models, and by specifying the results to many real physical systems.
		Then we studied the case of the Pump and Probe nonlinear processes and together with the discussion of the range of validity of the results coming from the usual Kramers-Kroenig analysis we presented the contributions due to terms of the susceptibility that previous analyses had neglected and discussed its physical relevance.

	APPLIED PHYSICS: ON EXTREME NONLINEAR OPTICS
		The EUV is a difficult region of the spectrum for nonlinear optics because traditional frequency-conversion techniques generally rely on crystalline solids as the nonlinear medium, and solids are not transparent in the EUV.
		Nevertheless, good reasons are driving the development of new light sources in that spectral range: Short-wavelength light is ideal as a structural and chemical spectroscopic probe and as a tool for nanoscale lithography.
		Moreover, the physics of the process differs radically from traditional nonlinear optics because it is intimately linked to the attosecond time domain.

	Laser Focus World - Fiber-laser SHG yields broad bandwidth at high power
		Nonlinear effects limit conversion efficiency as input fundamental IR beam power at 1064 nm exceeds about 2.5 W. Because the efficiency of the nonlinear crystals is polarization-dependent, to generate an efficient and stable second harmonic the polarization state of the fiber laser has to be stable.
		In the case of PPLN, the polarization state has to be linear and the field has to be polarized along the z-axis of the PPLN in order to utilize the most efficient d33 coefficient of the PPLN.
		Using a highly nonlinear optical fiber, we have Stokes-shifted the fiber laser from 1120 to 1586 nm.

		This "nonlinear Thomson scattering" causes the electrons to emit higher-frequency versions (harmonics) of the original laser light in a characteristic pattern.
		It was precisely the emission of harmonic light by intense light striking slow electrons bound to atoms (also at the University of Michigan) that helped to establish nonlinear optics in the early 1960's.
		Now the scattering of intense light from fast free electrons helps to establish an era of relativistic nonlinear optics, one goal being the generation of coherent x rays.
