Adaptive Wavefront Control with Coherent Fiber Array Systems
Hosted By: Laser Systems Technical Group
12 September 2022 16:00 - 17:00
Eastern Time (US & Canada) (UTC - 05:00)Fiber integrated elements of coherent (coherently combinable) fiber collimator array-based transceiver systems allow extremely fast (< 10-9 sec. time response) control of the outgoing phase (piston phase) at each fiber collimator subaperture. In systems with a large number of subapertures, this ultrafast wave front phase shaping offers the unparalleled and yet mostly unexplored possibilities for adaptive optics (AO) and engineering of laser beams with complex spatio-temporal characteristics, including the creation of laser beams with controllable coherence properties.
In this webinar hosted by the Laser Systems Technical Group, Mikhail A. Vorontsov will provide several examples of laser beam engineering and adaptive turbulence effects mitigation using coherent fiber array systems in the following three applications: (a) laser beam projection for achieving maximum power density at a remotely located target – the so-called directed energy application, (b) power beaming for optical power transfer over extended range distances for optical-to-electrical power conversion; and (c) laser illumination for scintillations and speckle-noise mitigation in active imaging.
Subject Matter Level: Intermediate - Assumes basic knowledge of the topic
What You Will Learn:
- Low- and high-power adaptive fiber array systems
- Target-in-the-loop turbulence effects mitigation with a coherent fiber array system (“cooperative” target)
