What is a Quantum Well Laser?

Lasers

Editorial Team - GoPhotonics

Feb 20, 2023

A Quantum well laser is a type of semiconductor laser where the thickness of the active region is very narrow. The thickness of the active region determines the wavelength of the light emitted by...read more

What is Mode Locking in Lasers?

Lasers

Editorial Team - GoPhotonics

Feb 10, 2023

Mode Locking is a technique to generate ultra-short pulses in the order of picoseconds (10-12) or femtoseconds (10-15). Lasers that generate a train of periodic ultra-short pulses are called mode-lock...read more

What is Spectral Hole Burning?

Lasers

Editorial Team - GoPhotonics

Feb 6, 2023

Spectral hole burning is the frequency selective bleaching of the absorption spectrum of an optically active material. It is a phenomenon that occurs in certain types of optical materials such as glas...read more

What are Distributed Bragg Reflector (DBR) Lasers?

Lasers

Editorial Team - GoPhotonics

Mar 20, 2023

A Distributed Bragg Reflector (DBR) Laser is a semiconductor laser with a p-n junction as an active medium and contains one or two Bragg reflectors on each side of the active region. Bragg reflectors ...read more

What are Gain-Guided Lasers and Index-Guided Lasers?

Lasers

Editorial Team - GoPhotonics

Feb 10, 2023

The goal of laser structures is to maintain a low threshold with high efficiency and a focused output beam. Gain guiding and Index guiding are two fundamental laser design strategies. A gain-guid...read more

What is Spatial Hole Burning?

Lasers

Editorial Team - GoPhotonics

Feb 7, 2023

Spatial hole burning is a phenomenon that occurs in laser systems when several light beams pass through a laser medium with inhomogeneous absorption. It refers to the process wherein some areas of the...read more

What are Ti:Sapphire Lasers?

Lasers

Editorial Team - GoPhotonics

Jan 16, 2023

The Ti:Sapphire laser (Ti:Al2O3 laser) is an efficient tunable solid-state laser that emits light in the visible and near-infrared region ranging from 650 to 1180 nm. This laser was first demonstrated...read more

What are Laser Cavity Modes?

Lasers

Editorial Team - GoPhotonics

Jan 31, 2023

Laser cavity modes are particular sets of standing wave patterns in a laser cavity. Standing waves, also known as stationary waves, are created when two waves of the same frequency and amplitude but o...read more

What is a Pockels Laser?

Lasers

Editorial Team - GoPhotonics

Feb 10, 2023

Pockels laser is a hybrid integrated laser made by integrating the pockels effect into a semiconductor laser. This laser has high-frequency modulation speed and fast switching by the integration of th...read more

What is Gain Switching in Lasers?

Lasers

Editorial Team - GoPhotonics

Feb 2, 2023

Gain switching is a method to generate short optical pulses in the order of picoseconds (10-12) in a laser by modulating the pump power or laser gain. An electrical or optical pumping can be provided ...read more

What are Solid-State Lasers?

Lasers

Editorial Team - GoPhotonics

Jul 13, 2023

Solid-state lasers are a type of laser where the lasing medium is a solid material, typically a crystal or glass, rather than a liquid or gas, doped with rare earth or transition metal ions. The conce...read more

What are Fiber Lasers?

Fiber Optics Lasers

Editorial Team - GoPhotonics

Aug 14, 2023

Fiber lasers are a type of solid-state laser that employ optical fibers as the gain medium. Unlike traditional gas or crystal-based lasers, fiber lasers utilize rare-earth-doped fibers, typically made...read more

What are the Properties of Laser Cavity Modes?

Lasers

Editorial Team - GoPhotonics

Feb 10, 2023

Laser cavity modes are particular sets of standing wave patterns in a laser cavity. Specific resonant modes, often referred to as cavity modes, are supported by the laser cavity and are distinguished ...read more

What are Red Lasers?

Global Lasers

Editorial Team - GoPhotonics

Aug 31, 2023

Red lasers are lasers that operate at wavelengths from 620 nm to 699 nm, which falls within the red spectral range of the electromagnetic spectrum. The typical emission of red lasers occurs at approxi...read more

What are the Effects of Laser Radiation on Human Body?

Lasers

Editorial Team - GoPhotonics

Jan 25, 2024

The biological impacts of laser radiation on human body are closely related to the wavelength, irradiance, and exposure duration. Laser radiation spans wavelengths from about 10,000 nanometers (nm) to...read more
