When a highly contrasted laser beam hits on the surface of leather, it quickly vaporizes or burns the leather. Laser engraving leather results in a debossed effect and a noticeable and clean contrast. Cutting leather with laser is incredibly fast and precise, making intr...
PROBLEM TO BE SOLVED: To provide a method for generating a wafer, which can reduce the probability that a chip is generated in the outer peripheral region of the wafer in a post-process. SOLUTION: A release layer is formed by irradiating a laser beam only to a central region of a ...
Laser devices, however, generate an intense beam of laser radiation that is all traveling in the same direction and with almost all of the light being of one specific wavelength.A green diode laser is 532 nm, while a Fiber Laser is between 780 nm and 2200 nm. A CO2 Laser is 10,600 ...
You can tell a sodium vapor light because it's really yellow when you look at it. A sodium vapor light energizes sodium atoms to generate photons. A sodium atom has 11 electrons, and because of the way they're stacked in orbitals one of those electrons is most likely to accept and ...
Like an LED, they make light when electrons and "holes" (effectively, "missing electrons") hop about and join together; like a laser, they generate coherent, monochromatic light. That's why they're sometimes referred to as laser diodes (or diode lasers). You can read more about them in...
to the positively biased anode and move towards it at a very high speed. Upon arrival at the anode, the high energy electrons lose energy through collisions with the metal atoms. Most of these electrons will do little more than heat the anode, but about 2% will generate x-rays in a ...
In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amaz...
Some plastics, like Plexiglass®, lend themselves more to cutting than others. The best results are obtained with acrylic (PMMA) plexiglass and polypropylene. This is because it can generate cuts with smooth edges without any scorch marks. ...
4: Laser Microphone A laser microphone worksby capturing vibrations off a plane, like a windowpane, for example, and transmitting the signal back to a photo detector, which converts the reflected laser beam into an audio signal. When sound hits the windowpane, it bends and causes the laser ...
A particle beam weapon would be able to generate power many times more destructive than any laser in development. Such a weapon would essentially be composed of two parts: a power source and an accelerating tunnel. If a functional particle beam weapon could be built, it would use its power ...
