In this article, the authors proposed an unhardened satellite telescope design based on a model of a missile warning satellite telescope developed by the American Physical Society Study Group on Boost-Phase Intercept Systems for National Missile Defense.Abstract:
Methods are proposed for hardening a missile warning satellite against jamming and damage from unlimited running time 1-MW airborne, 1-MJ ground-based, and space-based lasers. The unhardened telescope design is based on a model of a missile warning satellite telescope developed by the American Physical Society Study Group on Boost-Phase Intercept Systems for National Missile Defense. The APS telescope can step-stare or linearly scan. In response to an attack, laser warning devices can close a shutter at the first focal surface. Filter wheels in a collimated section of the optical path, insert filters to protect focal plane arrays and readout ICs from jamming and damage. Neutral density filters are inserted to assess threats. The shutter is reopened. The reduced laser intensity in the collimated section protects the filters. The field of view (FOV) is reduced with a field stop wheel, with differently sized apertures, to allow the system to step-stare between multiple jammers in the normal FOV. A cryogenic gas cools fore-optics heated by lasers or by X-rays from nuclear bursts.read more

Ground based laser triggered discharges on satellite solar arrays
TL;DR: In this article, ground-based lasers (GBLs) can be used to induce short circuits between solar cells on some satellite arrays, but the vulnerability does not exist in the arrays used on U.S. Milsats (military satellites).

Airborne laser threat to commercial space telescopes
TL;DR: In this article, an emerging airborne laser (ABL) threat to commercial and scientific space telescopes is described, and techniques for hardening commercial satellites against ABLs and ground-based lasers are presented.

Hardening GEO missile warning satellites against thermal jamming by out-of-band airborne lasers
TL;DR: In this paper, thermal radiation transport theory is used to show that cooling the walls of the fore-optics enclosure to ~ 130 K during an attack will adequately cool the scan mirror and protect the sensor from thermal jamming.

The ray guns are coming
TL;DR: The U.S. Navy's most advanced laser weapon looks like a pricey amateur telescope as discussed by the authors, and the operator sits in a darkened room elsewhere on the ship holding a game controller.
