    "abstract": "We present an experimental and numerical study of electron emission from a\nsharp tungsten tip triggered by sub-8 femtosecond low power laser pulses. This\nprocess is non-linear in the laser electric field, and the non-linearity can be\ntuned via the DC voltage applied to the tip. Numerical simulations of this\nsystem show that electron emission takes place within less than one optical\nperiod of the exciting laser pulse, so that an 8 fsec 800 nm laser pulse is\ncapable of producing a single electron pulse of less than 1 fsec duration.\nFurthermore, we find that the carrier-envelope phase dependence of the emission\nprocess is smaller than 0.1% for an 8 fsec pulse but is steeply increasing with\ndecreasing laser pulse duration.",
