Pulses Shaped at Fs Frequency
WEST LAFAYETTE, Ind., Aug. 1, 2007 -- Engineers have finely controlled the spectral properties of ultrafast light pulses, a step toward creating advanced sensors, more powerful communications technologies and more precise laboratory instruments.
The laser pulses could be likened to strobes used in high-speed photography to freeze fast-moving objects such as bullets or flying insects. These laser pulses, however, are millions of times faster than such strobes, with flashes lasting a trillionth or quadrillionth of a second -- a...
