The HELIOS system uses a modular power and fiber-optic configuration that can be expanded to fire at between 60 and 120 kW. Besides drone and missile defense, it also performs long range surveillance and sensor dazzling. Its purported advantages are high precision, efficient "cost to kill", and power capacity for multiple shots. [1]
AN/ASQ-228 Advanced Targeting Forward-Looking Infrared (ATFLIR) Pod on an F/A-18 Super Hornet. F-4 Phantom shown from an ATFLIR Targeting Pod. The AN/ASQ-228 Advanced Targeting Forward-Looking Infrared (ATFLIR) is a multi-sensor, electro-optical targeting pod incorporating thermographic camera, low-light television camera, target laser rangefinder/laser designator, and laser spot tracker ...
A laser warning receiver is a warning system used as a passive military defence. It detects, analyzes, and locates directions of laser emissions [ 1 ] from laser guidance systems and laser rangefinders .
In optical parametric generation, the input is one light beam of frequency ω p, and the output is two light beams of lower frequencies ω s and ω i, with the requirement ω p =ω s +ω i. These two lower-frequency beams are called the "signal" and "idler", respectively. This light emission is based on the nonlinear optical principle.
FROG is currently the standard technique for measuring ultrashort laser pulses replacing an older method called autocorrelation, which only gave a rough estimate for the pulse length. FROG is simply a spectrally resolved autocorrelation, which allows the use of a phase-retrieval algorithm to retrieve the precise pulse intensity and phase vs. time.
The Advanced Target Pointer Illuminator Aiming Laser, ATPIAL AN/PEQ-15 known colloquially as the "PEQ-15" [/ p ɛ k / / f ɪ f t iː n /] produced by L3Harris (originally designed and manufactured by Insight Technology, until their acquisition by L3Harris in 2010); is a multifunction IR Target Pointer & Illuminator, a.k.a. a Laser Aiming Module (LAM) for use as a rifle attachment, using a ...
The Leddar technology is like a light-based radar that sends very short light pulses of invisible light about 100,000 times per second to actively illuminate an area of interest. The sensor captures the light backscattered from objects (either fixed or moving) over its detection area and processes the signals to precisely map their location and ...
Optical frequency multipliers are common in high-power lasers, notably those used for inertial confinement fusion (ICF) experiments. ICF attempts to use a laser to heat and compress a target containing fusion fuel, and it was found in experiments with the Shiva laser that the infrared frequencies generated by the laser lost most of its energy in the hot electrons being generated early in the ...
