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 ...

Laser drilling has found many applications in precision machining, microelectronics, chip fabrication, tablet drilling, and dentistry. The high aspect ratio of this process and its non-contact nature ...

Introduction We frequently use disk laser welding in the manufacturing sector (e.g., see Figure 1). The laser beam interacts with the material to carry the welding energy, with the result that some of the ...

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 ...

You might have heard that lasers can be used in treating kidney stones. The method – often referred to as laser lithotripsy – has become a standard tool in urology. In this article, we will ...

Talking to one another or throwing a rock in a still pond will create waves that affect the mass around the epicenter, creating peaks and troughs. Similar to sound or water waves, gravitational waves are ...

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 ...

Introduction Photonics has a wide array of applications in data communications, imaging, light sensing, and surgery. One such field where the utilization of light is particularly useful is ophthalmology. ...
