Introduction to laser powder bed fusion In this article, we discuss a novel work introduced by the researchers at the Lawrence Livermore National Laboratory and University of Nebraska-Lincoln in the USA. ...

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 ...

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 ...

Ever wonder how facial recognition has come around to be implemented in smartphones today? Vertical cavity surface-emitting lasers, (abbreviated VCSEL, pronounced “vixel”) are to thank for such ...

What is a Laser Microphone? Laser microphones are any device that uses a laser or optical beam to recover audio information, largely these devices use mechanical disturbance of the laser’s beam ...

Hunting. What was a pursuit once necessary for survival is now a sporting pastime for those in the developed world. Many of the animals are nocturnal which makes the night time a preferred time for ...

One area where photonics is integrated prolifically is the aerospace and defense world. Giants of the aerospace and defense industry rely heavily on implementing photonics technologies to successfully ...

Today’s blog post is sponsored by Horiba – a leading manufacturer of spectroscopy and material analysis solutions. Most people have experienced the frustration of traffic signals. The lights change at the ...

Both LiDAR and RADAR are well-established methods of detection and remote sensing. Some systems benefit from using radar while others are better served using LiDAR. In some cases, the two techniques may ...
