[17] In 2015, XTR Signature Rings was launched as a further development of the Burris Signature ...
Some scope bases, such as Leupold & Stevens's proprietary STD mounts, use socketed bases screw-fastened to the receiver and a twistlock-like interface to secure the accompanied scope rings. An alternative design that has remained popular since the early 20th century is the dovetail rail , which is a straight metal flange with an inverted ...

Metals can not be easily be engraved with common 10,600 nm [5] wavelength CO 2 lasers, on account of many metals having high reflectivity around this wavelength. Yb:Fiber Lasers, Nd:YVO 4 , both emitting light of approximately 1000 nm wavelength, Nd:YAG lasers at 1,064 nm wavelength, or its harmonics at 532 and 355 nm, emit light that is more ...
Laser science predates the invention of the laser itself. Albert Einstein created the foundations for the laser and maser in 1917, via a paper in which he re-derived Max Planck’s law of radiation using a formalism based on probability coefficients (Einstein coefficients) for the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation.
