Colored conical emission by means of second-harmonic generation
Optics Letters
|November 21, 2007
Summary
We predict that combined space and time modulational instabilities in quadratic media will generate colored conical emission. This effect is observable under typical second-harmonic generation experimental conditions.
Area of Science:
- Nonlinear Optics
- Wave Propagation Physics
Background:
- Parametric wave mixing in quadratic nonlinear media is a fundamental process.
- Modulational instabilities can arise in both spatial and temporal domains.
Purpose of the Study:
- To predict the occurrence of colored conical emission.
- To investigate the combined effects of spatial and temporal modulational instabilities.
Main Methods:
- Theoretical analysis of wave mixing in quadratic media.
- Modeling of coupled spatial and temporal modulational instabilities.
Main Results:
- The interplay of space and time modulational instabilities leads to the generation of colored conical emission.
- This phenomenon is predicted to occur under standard second-harmonic generation experimental setups.
Conclusions:
- Colored conical emission is a predictable outcome of combined modulational instabilities.
- Experimental verification is feasible using existing second-harmonic generation techniques.

02:39Emission Spectra
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.
01:10Generating Electromagnetic Radiations
The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...
02:26Photoelectric Effect
When light of a particular wavelength strikes a metal surface, electrons are emitted. This is called the photoelectric effect. The minimum frequency of light that can cause such emission of electrons is called the threshold frequency, which is specific to the metal. Light with a frequency lower than the threshold frequency, even if it is of high intensity, cannot initiate the emission of electrons. However, when the frequency is higher than the threshold value, the number of electrons ejected...
