According to Raydiance, the R-Cut combines an ultra-short pulse laser and micromachining processes to cut very hard and brittle materials very quickly and with less chance of their chiping or shattering. It's based on a femtosecond laser, which is generated by a technique called chirped pulse amplification that produces a burst of laser light that lasts one quadrillionth of a second. This is so short that during its pulse, the laser will only travel 1/100th the width of a human hair.
Designers have used new materials, such as Gorilla glass and sapphire to make phone displays lighter and more durable, but these have introduced their own problems – especially when it comes to manufacturing. Gizmag spoke with Raydiance, a company specializing in cutting-edge laser fabrication methods, about its new R-Cut femtosecond laser system that promises a "new paradigm" in high-tech glass fabrication.
