[Jerry] missed the laser cutters he had been using at the local TechShop. It closed down and after seeing some hardware in a surplus store he decided to build a laser cutter to call his own.

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240003 , discusses a three-dimensional multichannel ...

Researchers from Tohoku University and the Massachusetts Institute of Technology (MIT) have unveiled a new AI tool for ...

Inspired by techniques used in industry, [Les] eventually tried to use a several-kW nitrogen laser to burn off the ... aren’t just for examining light spectra—they can also be used to judge ...

The Series 3500 UV lasers from DPSS Lasers (Santa Clara, California, USA) are quasi-continuous-wave (quasi-CW) lasers with a repetition rate greater than 100 kHz.

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

The objective of the research in the atomic and molecular laser spectroscopy laboratory is to gain knowledge about the basic properties of ions and neutral atoms and molecules, with a particular ...

he tells Physics World. The NIST/University of Maryland team has been working on optical parametric oscillation as a way to convert near-infrared laser light to visible laser light for several years ...

How quantum physics could help lasers perform better in fog and aid communications A team of researchers at Washington University in St. Louis has drawn on quantum physics to develop a new ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

Experimental atomic, molecular and optical physics offers rich avenues of explorations and understanding of atoms and molecules and their interaction with light. Students will gain hands-on experience ...
