WebIt is limited by the finite velocity of sound in the acousto-optic medium. This implies that an AOM switching a laser beam with large diameter is necessarily slow. One may operate such a modulator with a focused laser beam of reduced diameter, but the diffraction efficiency may decrease due to the increased beam divergence.

The Limits Of Lasers: Missile Defense At Speed Of Light
WebMar 11, 2005 · Unfortunately, silicon has an appetite for eating laser photons. When an incoming laser pulse — known as the pump pulse — is trained on silicon, silicon atoms can absorb two photons simultaneously. … WebApr 11, 2024 · Multiple reports reveal the tank has rather advanced countermeasures such as a “TShu-1-7-Shtora-1” optronic system to disrupt laser targeting on incoming ATGMs and an electro-optical jammer. Perhaps of greatest significance, the T-90M is engineered with advanced thermal sights, as high-fidelity, long-range targeting sensors can of course ... WebJul 7, 2024 · Physicists at MIT have designed a quantum “light squeezer” that reduces quantum noise in an incoming laser beam by 15 percent. It is the first system of its kind to work at room temperature, making it amenable to a compact, portable setup that may be added to high-precision experiments to improve laser measurements where quantum … theowandthewife
