LCLS is a DOE Office of Science User Facility.
"When a wave of light reaches the apex of a cone, it diffracts and leaves the surface as coherent light [light that focuses like a laser]," Kazan said.

Thomas Furness, a professor at the University of Washington, recognized that every material exhibited a unique light signature when stimulated by visible and invisible structured coherent light sources.
The classic double-slit experiment is simple to execute, requiring only a coherent light source such as a laser pointer, a screen and a plate with two thin parallel slits.
In recent years, the partially coherent light under tight focusing finds huge applications such as optical communication, optical sensors, optical data storage, optical manipulation, microscopy, material processing, microparticle trapping manipulation, and optical measuring instruments [1-8].
Assume that focused coherent light is incident on a sample, where a small absorptive semihomogeneous objective region is in the background of a homogeneous transparent one.
Since then, medical treatment with coherent light sources (lasers) or non coherent light (LEDs) has passed through its experimental stage and is firmly rooted in clinical and scientific documentation.
