The carrier-envelope phase (CEP) or carrier-envelope offset (CEO) phase is an important feature of an ultrashort laser pulse and gains significance with decreasing pulse duration, in a regime where the pulse consists of a few wavelengths. Physical effects depending on the carrier-envelope phase fall into the category of highly nonlinear optics.
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).
The Visible light is located on the opposite side to the laser module, but cannot be activated with the laser in order to prevent white light discharge, and pollution. As part of the M27 IAR rollout in 2011, a number of standard accessories were chosen to be included with every M27, including an AN/PEQ-16 to allow for improved night and day ...
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of ... A 5.6 mm 'closed can' commercial laser diode, ...
A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating (Bragg scattering), and the grating provides optical feedback for the
Industrial laser cutting of steel with cutting instructions programmed through the CNC interface. The laser beam is generally focused using a high-quality lens on the work zone. The quality of the beam has a direct impact on the focused spot size. The narrowest part of the focused beam is generally less than 0.0125 inches (0.32 mm) in diameter.
French squads include a 300 Meter fireteam called "Équipe Alpha" (consisting of a team leader armed with a Heckler & Koch HK416 and two grenadiers-voltigeurs, each armed with a Heckler & Koch HK416 assault rifle as well as an AT4 anti-tank weapon) and a 600 Meter fireteam or "Équipe Bravo" (again with a team leader equipped with Heckler & Koch HK416 and two grenadiers-voltigeurs as well with ...
The rotating mirror at the end of the imaging head rotates around its axis to beam the laser on the desired part of the fixed plate. The construction type makes it more difficult to use several lasers at the same time, but just using one laser also has advantages such as uniform beam intensity over the whole plate imaging period.
