Some lasers use pumping systems, methods of increasing the energy of particles in the laser medium that let them reach their excited states to make population inversion. A gas flash lamp can be used in optical pumping that carries energy to the laser material. In cases where the laser material...
is fused by absorbing laser beams (L1, L2) through the test plate; a step for forming a modified layer, wherein the test film is made to be opposite to a retaining surface (4a) of a chuck workbench (4) by using the chuck workbench to retain the test plate, and the laser beam emit...
Scattering has another trick up its sleeve, however - the scattered light can interact with the original laser light to make the original laser light scatter in the direction of the scattered light. In effect, this turns the air into another laser, powered by the original laser beam and ...
When a laser beam is propagating freely, it will naturally tend to expand. This means that if you try to focus the beam down to a tiny point at a distant target, the beam might spread out to a much larger spot by the time it gets there. The amount the beam expands depends on the...
How does an excimer laser work? Excimer Laser: Lasers are devices that use the principles of optical superposition to create coherent light beams. This allows the creation of extremely narrow, intense light beams at high frequency over large distances and with great power. ...
There are lots of different ways to arrange these tools — we'll stick to a basic transmission hologram setup for now. The laser points at the beam splitter, which divides the beam of light into two parts. Mirrors direct the paths of these two beams so that they hit their intended target...
Lightning rods that use laser beams can efficiently (and safely) guide bolts of lightning, preventing random strikes, scientists explain. Here’s how they work.
structured light 3D scanners, laser triangulation-based scanners, time-of-flight laser scanners, and others. Structured-light devices likeArtec Leoemit beams of white light in a grid format, in a way that allows small-to-medium sized objects to be digitized in high resolution, with complete ...

King Caesar, such an interesting kaiju and one of my favorite kaiju of the Showa series. People seem to really want to see king Caesar make a comeback in one of the legendary movies. For a while, I thought he would be too similar to Mothra seeing ...
