Crimson Trace is an American manufacturer of laser sight equipment, chiefly but not exclusively for pistols. The firm specializes in in-line upper-grip-mounted red and green laser units, trigger-guard mounted sights, and training units. Crimson Trace partners with manufacturers of firearms in product releases, with many models shipping with ...
Yellow dots on white paper, produced by color laser printer (enlarged, dot diameter about 0.1 mm) Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code (MIC), is a digital watermark which many color laser printers and photocopiers produce on every printed page that identifies the specific device that was ...
Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates .
Laser marking on stainless steel A laser engraving machine A laser engraver. A laser engraving machine consists of three main parts: a laser, a controller, and a surface. [2] The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface.
Inside the laser shell is the PCB with sensors and lights, a speaker to indicate the status of the pack, a trigger, and an LCD to display the status of the pack to the player. The IR unit is what emits the visible laser the eye sees and the invisible IR beam which "tags" the opponent's packs. The laser has a display in the rear.
Disc rot is the tendency of CD, DVD, or other optical discs to become unreadable because of chemical deterioration. The causes include oxidation of the reflective layer, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together.
Lasers are used to treat cancer in several different ways. Their high-intensity light can be used to shrink or destroy tumors or precancerous growths. Lasers are most commonly used to treat superficial cancers (cancers on the surface of the body or the lining of internal organs) such as basal-cell skin cancer and the very early stages of some cancers, such as cervical, penile, vaginal, vulvar ...
As the common visible-light laser transitions between electronic or vibrational states correspond to energies up to only about 10 eV, different active media are needed for X-ray lasers. Between 1978 and 1988 in Project Excalibur the U.S. military attempted to develop a nuclear explosion-pumped X-ray laser for ballistic missile defense as part ...
