Are superconductors perfect reflectors?

Having spent the past three years literally shining powerful lasers onto superconductors and measuring the reflectivity I can confirm that they are *not* perfect reflectors. Optical alignment would have been so much easier if they were.

Will a mirror reflect a laser?

It will bounce off at the same angle it hit. If you shine a laser on a mirror, you can only see the light if you are in the direction it bounces, and then it looks like the light came from behind the mirror. It will still look like it came from behind the mirror. This is what we call a reflection.

Can a laser pierce a mirror?

if you get a powerful enough laser, can it burn through a mirror, or will it always be reflected? A: In principle you can burn through any mirror if the laser is strong enough. The absorption coefficient of the very best mirrors is of the order of 1 part per million.

Can a mirror deflect a powerful laser?

The many tiny layers (visible along the bottom edge) that make up a dielectric mirror give it a reflectivity of up to 99.99 percent, allowing it to effectively deflect lasers and protect drones. Ryan Hoffman, Counter-Directed Energy program manager, says that mirrors protect well against low-power lasers.

Do perfect mirrors exist?

Almost any dielectric material can act as a perfect mirror through total internal reflection. A new type of dielectric “perfect mirror” was developed in 1998 by researchers at MIT. These unusual mirrors are very efficient reflectors over a broad range of angles and wavelengths, and are insensitive to polarization.

Are perfect reflectors common?

Perfect reflectors are common. c. The manner in which light is reflected from a surface depends on the surface’s smoothness. All substances absorb at least some incoming light and reflect the rest.

Can a mirror deflect all lasers?

The actual answer is no, it can’t. Even a mirror that reflects 95\% of a lethal laser beam will still absorb enough heat to burn. This causes the reflectivity to be gone almost instantly, but a scattered burst of light from the point of impact could still blind the shooter or his allies.

Are mirrors perfect reflections?

It offers a perfect reflection. The mirrors in our homes usually have a thin layer of metal sealed beneath a layer of glass. Light travels through the glass, reflects off of the metal and bounces back through the glass. But the mirror absorbs some light.
