Regarding the military laser China used affecting two servicemen. Do we know what wavelength and frequency this Mortuary laser was using?

2018-05-05T16:00:19-04:00

I don't know if anyone in our military is familiar with the concept or not. We can use coherent perfect absorbers, and utilization as an antilazer. It works as a laser in reverse. By absorbing photonic light well at the same time and doing so disrupting photonic activity at the source point of the laser.

At what incident angle(s)?

WAY over my head, Erin Nelson. LOL Nice to see you back on here though.

There is no critical angle when the refractive index of the medium containing the incident ray is less than the medium with the transmitted ray.

Dazzler (weapon) - Wikipedia

A dazzler is a non-lethal weapon which uses intense directed radiation to temporarily disable its target with flash blindness. Targets can include sensors or human vision.

Coherent perfect absorber - Wikipedia

A coherent perfect absorber (CPA), or anti-laser, is a device which absorbs coherent light and converts it to some form of internal energy such as heat or electrical energy.[1][2] It is the time reversed counterpart of a laser.[3] The concept was first published in the July 26, 2010, issue of Physical Review Letters, by a team at Yale University led by theorist Douglas Stone [4][5] In the September 9, 2010, issue of Physical Review A, Stefano...

As I'd said, a simple consideration of Snell's law, as well as angle of incidence, will only begin to scratch the surface of a topic as complex as the one you raised...I'll suggest mere in a cpl of minutes, however, trust me, while I can appreciate the tech iCal complexity of the problem, I can, simultaneously, envision just how complex trying to model it properly would be, I assure you....
