Optical Pumping - Definition and Applications

Article - 12 Mar 2014

Optical pumping is a process in which light energy is used to excite electrons from a lower to higher energy level. It was first developed by Alfred Kastler in the early 1950s. It is primarily used to...
Stabilizing Chiral Microstructure Micromachining with a Multiramp Helical-Conical Beam

News - 25 Oct 2022

In an article published in Micromachines, researchers introduced a multiramp helical-conical beam (MHCB) that could generate three-dimensional (3D) spiral light fields in a sharply focused...
NIST Researchers Solve the Mystery of Degrading Sunlight Detectors

News - 26 Mar 2021

More than 150 years ago, the Sun blasted Earth with a massive cloud of hot charged particles. This plasma blob generated a magnetic storm on Earth that caused sparks to leap out of telegraph equipment...

News - 8 Jul 2015

Serving as the preeminent forum in Asia for lasers and electro-optics disciplines ranging from laser physics to system engineering and applications, the 2015 Conference of Lasers and Electro-Optic...
Using Dielectric Thin Films for Optical Coatings

Article - 17 Jul 2023

An anti-reflection coating is a dielectric thin film coating with a specific refractive index and thickness. The coating is applied to an optical surface to reduce the reflectivity/reflectance of that...
Using Laser Fusion to Generate High Power Lasers

Article - 11 Feb 2020

The staple of high-powered lasers was established in 1996 when the method of chirped-pulse amplification was used to create the world's first petawatt pulse with the Nova laser. Scientists have since...
The Different Types of Lasers and Lasing Media

Article - 14 May 2018

There are thousands of different types of lasers which are divided into different types according to the lasing medium they use. The most common ‘types’ of laser are gas, liquid, solid-state and...
Measuring the Exciton Valleys in WSe2

Article - 13 Apr 2017

Excitons, also referred to as Coulomb bound electron-hole pairs, are composite bosons which lead to condensation and light amplification processes in semiconductors.
Gain Medium - Definition and Use in Laser Construction

Article - 31 Jan 2014

Gain medium is a quantum system that amplifies laser beams by means of stimulated emission.
