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 ...

  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 ...

Do you have a new prototype and want to test it within hours? Welcome to the world of 3D printing. By layering the 3D object from the ground up by using thermoplastics or metals, people around the world ...

You have probably heard of UV disinfecting and have also probably seen some commercial products readily available in the market. But do you know how they work? How they produce the UV rays and whether they ...

Introduction Microresonators have been the topic of interest for many research groups for their unique properties, compactness, ease of fabrication, and versatility. They are essentially optical cavities ...

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 ...
