The RP Photonics Encyclopedia (formerly Encyclopedia of Laser Physics and Technology) is an encyclopedia of optics and optoelectronics, laser technology, optical fibers, nonlinear optics, optical communications, imaging science, optical metrology, spectroscopy and ultrashort pulse physics. [1] It is available online as a free resource.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).

Since a laser beam has low divergence, the laser light appears as a small spot even at long distances; the user places the spot on the desired target and the barrel of the gun is aligned (but not necessarily allowing for bullet drop, windage, distance between the direction of the beam and the axis of the barrel, and the target mobility while ...
Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. [ 1 ] Laser science is principally concerned with quantum electronics , laser construction , optical cavity design, the physics of producing a population inversion in laser media , and the temporal evolution of the light field in the laser.
The photon of an incident laser pulse (pump) is, by a nonlinear optical crystal, divided into two lower-energy photons. The wavelengths of the signal and the idler are determined by the phase matching condition, which is changed, e.g. by temperature or, in bulk optics, by the angle between the incident pump laser ray and the optical axes of the ...
where is the electron charge, is the linearly polarised electric field amplitude, is the laser carrier frequency and is the electron mass. In terms of the laser intensity I {\displaystyle I} , using I = c ϵ 0 E 2 / 2 {\displaystyle I=c\epsilon _{0}E^{2}/2} , it reads less simply:
A PDF creator and virtual PDF printer for Microsoft Windows PDF-XChange: Proprietary: Yes: PDF Tools allows creation of PDFs from many types of source input (images, scans, etc.). The PDF-XChange print driver allows printing directly to a PDF. A "lite" version of the print driver is free for non-commercial (home and academic) use. PrimoPDF ...
