Silver across frequencies, but engineered substances, the type used in laser safety devices, can have very good reflection at specific wavelengths without the weight of silver. For a flying object at any distance, anything close to 90% reflectivity for a few seconds would radically extend survival time. Local burn through can be survived as the beam will by dancing across the target.
- jandrewrogers 4y agoSome of these lasers are effectively white light by design. You can design dielectric mirrors against one frequency but not all frequencies.
- sandworm101 4y agoWhite lasers only look white by mixing a handful of colours. That's why laser safety goggles are still transparent, they only block those frequencies known to be generated by current laser tech.
- chipsa 4y agoSupercontinuum lasers are actually white, in that they are a broad range of frequencies of light. It is recommended you don't try to use laser safety googles with them, as there is no specific frequency you can guard against. Whether this applies to the weapons power laser discussed is another question entirely.
