Flaw detection and rapid fatigue fracture Additive manufacturing (AM) techniques have gained popularity in a number of high-value industries due to their capacity to produce small batches of geometrically ...

How often do we think about the importance of optical fiber probes in biomedical applications? When we think of optical engineering applications in the medical field, we often think of lasers, MRI ...

Introduction Supercontinuum lasers are a special type of lasers that emit an extremely wide and continuous spectrum of light. When they were first invented, these lasers were known as the “white-light” ...

Introduction Using the technique of keyhole laser welding, we can use very high beam intensities to process the material (please see this reference for the details of keyhole laser welding technique). Due ...

Stimulated emission depletion microscopy (STED) is a popular super-resolution microscopy technique that researchers use to magnify microscopic organic compounds and proteins. This method is superior to ...

  Have you ever considered how small something could be? What would limit how small we can make things? How precise exactly is “ultra precision”? Today we will have an introduction into ...

Introduction In this article we will discuss the use of HWG and PIR fibers for CO2 and CO laser beam delivery. Since their invention over half a century ago, CO2 and CO lasers have attracted the attention ...

Introduction Nowadays, we see the application of artificial intelligence in many places, whether we are a student in a university or an engineer working in an industrial company. Artificial intelligence ...

If you’ve visited an optometrist, they may have used optical coherence tomography (OCT) to scan your retina. This new technique uses low coherence interferometry to image semi transparent tissue. Being a ...

Why do We Need Deformable Mirrors? Deformable mirrors are specialty mirrors that are capable of deforming their reflective surface and thus achieve wavefront correction of optical aberrations. In astronomy ...
