Lannan Neville Eacott [1] (born 14 December 1994), better known as LazarBeam, is an Australian YouTuber, professional gamer and Internet personality, known primarily for his video game commentary videos, "comedic riffs" and memes.
The beam of a single transverse mode (gaussian beam) laser eventually diverges at an angle that varies inversely with the beam diameter, as required by diffraction theory. Thus, the "pencil beam" directly generated by a common helium–neon laser would spread out to a size of perhaps 500 kilometers when shone on the Moon (from the distance of ...
E - Laser beam. F - Pumping cavity. G - Ruby rod. H - Trigger wire. A ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. The first working laser was a ruby laser made by Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960. [1] [2]
In late 2017, IPG announced the acquisition of Laser Depth Dynamics, a provider of an optical coherence tomography-based in-process quality monitoring and control solutions for laser-based welding applications. [29] The subsidiary operates as IPG Photonics (Canada) Inc. and is located in Kingston, Ontario. [30]
The Iron Beam concept, as a part of a multi-layered defense, was announced at the Singapore Airshow in 2014. [19] A demonstrator Laser Weapons System was operating by 2017. [20] An Iron Beam battery is composed of an air defense radar, a command and control (C2) unit, and two HEL (high-energy laser) systems.
On February 26, 2009, NIF fired all 192 laser beams into the target chamber. [100] On March 10, 2009, NIF became the first laser to break the megajoule barrier, delivering 1.1 MJ of UV light, known as 3ω (from third-harmonic generation), to the target chamber center in a shaped ignition pulse. [101] The main laser delivered 1.952 MJ of IR. [102]
The death ray or death beam was a theoretical particle beam or electromagnetic weapon first theorized around the 1920s and 1930s. Around that time, notable inventors such as Guglielmo Marconi , [ 1 ] Nikola Tesla , Harry Grindell Matthews , Edwin R. Scott , Erich Graichen [ 2 ] and others claimed to have invented it independently. [ 3 ]
Laser beam machining (LBM) is a form of machining that uses heat directed from a laser beam. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. The high frequency of monochromatic light will fall on the surface, thus heating, melting and vaporizing the material due to the impinge of photons (see Coulomb ...
