The Kerr effect (also known as quadratic electro-optic effect) is a phenomenon observed in non-linear optic materials where the refractive index of the material changes in response to an electric field.
The argon laser is a unique gas laser, as it uses a noble gas (argon) as the active medium. It is commonly referred to as argon ion laser.
Thulium-yttrium aluminum garnet (Tm:YAG) laser is used as a suitable means to produce high power laser emission from the 3F4 – 3F6 transition.
The aluminium gallium indium phosphide laser is a type of visible-light diode laser. Visible diode lasers emit wavelengths of red and green in the visible spectrum of electromagnetic radiation.
Optical rectification or electro-optic rectification may be described as a non-linear optical process that generates a quasi-DC polarization in a non-linear medium by passing an intense beam of light.
Optical cross phase modulation (XPM) may be described as a non-linear optical process where the wavelength of one light source affects the phase of another wave.
Metal halide lamps or metal halide arc lamps consist of a high performance arc discharge tube housed in an elliptical reflector that focuses the output into a microscopic optical train. The arc tube is filled with metal halide salts.
Sum frequency generation (SFG) may be defined as a second order non-linear optical process in which a tunable infrared beam is combined with a visible beam, such that that the frequency of the output beam is the sum of the input frequencies.
Acousto-optics is a phenomenon which deals with the interaction of light (optics) and sound (acoustics). The existence of an interaction between light and sound was discovered by Brillouin in the year 1922.
Advancements in smartphones are continuing to progress with an effort to making these phones capable of being applied in sophisticated fields of application including laboratory analysis.
