The emergence of convenient sources of broadband light spanning the visible and near-infrared is ... reports Neil Savage. Lasers are useful because they produce powerful beams of collimated ...

Lasers are known for the monochromatic nature ... Basically, a “supercontinuum” is just the conversion of a monochromatic source to a broader spectral bandwidth. It’s a non-linear optical ...

Using a green laser beam, a ruby crystal, and blue light illumination, they demonstrated that light, under specific conditions, could block another light source, creating a visible shadow.

Scientists are developing miniature lightsails that could travel at unprecedented speeds, potentially enabling interstellar ...

Ultrawide-bandgap semiconductors—such as diamond—are promising for next-generation electronics due to a larger energy gap ...
