Raydiance
Schuler wants Raydiance lasers to replace standard cutting tools in every industry, from lumberyards to aerospace factories.
Raydiance
CEO: Barry Schuler
Disruption: Lasers that cut without heating surrounding material
Disrupted: The entire laser industry -- medicine, aerospace, and beyond

Raydiance's ultrashort pulse laser is more accurate than the standard fare in the industry, and when properly tuned, it can blast away at anything from a hunk of steel to a single cancer cell. Though researchers have been using USP lasers since 1989, they've been unmanageably large and notoriously difficult to operate - but Raydiance has managed to shrink its product down to the size of a microwave.
