From microsaws to nanodrills: laser pulses act as subtle machining tools: Industrial-grade materials processing on the sub-micron scale is enabled by spatially structured ultrashort laser pulses

Date:

If light is strongly concentrated in time and space, resulting in extreme photon densities, it can enable interaction with all conceivable materials. By using these ultrashort laser foci, even transpa… Source: http://www.nanotech-now.com/news.cgi?story_id=56578
