Quantum Dot Laser – a type of semiconductor laser

A quantum dot laser is a semiconductor laser in which quantum dots serve as the active medium. It is a semiconductor laser with a light…
Thermo-optic Coefficient

Thermo-optic Coefficient

A material’s thermo-optic coefficient is the change in refractive index as a function of temperature. This value is likewise affected by the material’s current temperature…
Cyclotron Turnover

Cyclotron Turnover

One of two mechanisms that cause the power spectrum of synchrotron radiation to drop at very low frequencies is cyclotron turnover. Synchrotron self-absorption is the…
Total External Reflection

Total External Reflection

Total external reflection is a phenomena that, in theory, can involve any sort of electromagnetic or other wave and is closely connected to total internal…
Synchrotron Radiation

Synchrotron Radiation

Synchrotron radiation is a type of electromagnetic radiation produced when charged particles, mainly electrons, are accelerated in a circular route within a synchrotron facility. It…
Cyclotron Radiation

Cyclotron Radiation

The electromagnetic radiation released by non-relativistic speeding charged particles deflected by a magnetic field is known as cyclotron radiation. It is a type of electromagnetic…
Ring Lasers

Ring Lasers

Ring lasers are made up of two beams of light with the same polarization going in opposite directions in a closed loop (“counter-rotating”). These are…
Total Internal Reflection – in Physics

Total Internal Reflection – in Physics

Total internal reflection (TIR) is the phenomenon in which waves arriving at the interface (boundary) of one medium to another (e.g., water to air) are…
Free-electron Laser

Free-electron Laser

A free-electron laser (FEL) is a fourth-generation light source that produces exceptionally bright and brief radiation pulses. It is a type of laser that uses…
Optical Ring Resonator

Optical Ring Resonator

An optical ring resonator is a collection of waveguides, at least one of which is a closed loop with light input and output. (These can…
Active Laser Medium

Active Laser Medium

The active laser medium (also known as a gain medium or lasing medium) is the source of optical gain within a laser. The gain is…
Laser Science – a branch of optics

Laser Science – a branch of optics
