A group of scientists led by the US Department of Energy's National Renewable Energy Laboratory (NREL) has designed a monocrystalline mini solar panel that can convert laser light into electricity.

However, for many other applications, especially those requiring intense laser light — such as marking ... brightness and low divergence (as small as 0.1 degrees) vertically from the top.

Part of the challenge is that the optical fiber inside the cladding is often very small ... laser precisely. The effects can be interesting; we had no idea comms-grade fiber could leak as much ...
