Synergetics is an interdisciplinary science explaining the formation and self-organization of patterns and structures in open systems far from thermodynamic equilibrium.It is founded by Hermann Haken, inspired by the laser theory.
Hermann Haken (12 July 1927 – 14 August 2024) was a German physicist and professor emeritus in theoretical physics at the University of Stuttgart.He is known as the founder of synergetics and one of the "fathers" of quantum-mechanical laser theory.
In an OPA, the input is two light beams, of frequency ω p and ω s. The OPA will make the pump beam (ω p) weaker, and amplify the signal beam (ω s), and also create a new, so-called idler beam at the frequency ω i with ω p =ω s +ω i. In the OPA, the pump and idler photons usually travel collinearly through a nonlinear optical crystal.
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 ...
HK MK23 with KAC suppressor and AN/PEQ-6 LAM mounted. The AN/PEQ-6 Integrated Laser Light Module (ILLM) is a laser aiming module (LAM) designed and manufactured by Insight Technology [1] [2] for use by United States Special Operations Command (USSOCOM) with the Heckler & Koch Mark 23 semi-automatic pistol and a Knight's Armament Company suppressor; the whole system is designated the Mk 23 Mod ...
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).
On the other hand, the light from a semiconductor laser typically exits the tiny crystal with a large divergence: up to 50°. However even such a divergent beam can be transformed into a similarly collimated beam employing a lens system, as is always included, for instance, in a laser pointer whose light originates from a laser diode. That is ...
