Researchers have found a way to generate the shortest - ever flash

long.
Ultrafast lasers have measured how
long electrons take to be booted from a helium atom with zeptosecond precision — trillionths

The researchers fixed a three centimetre
long diamond strip, just 0.3 millimetre thick, in a specimen holder and triggered a shock wave with a brief flash from a powerful infrared laser that hit the narrow edge
of the diamond; this pulse lasted 0.15
billionths of a
second (150 picoseconds) and reached a power level
of up to 12 trillion watts (12 terawatts) per square centimetre.

The scientists let strong, approximately four - femtosecond -
long laser pulses hit the group

When co-author Zhaoming Zhu, Gauthier's postdoctoral research associate, encoded information onto one
of these beams, the data could be imprinted on these newly created phonons and retained for 12
billionths of a
second,

This «serial time - encoded amplified microscopy» (STEAM) camera creates each image using a very short laser pulse — a flash
of light only a
billionth of a
second long.
This technology can zoom in on objects as small as a few nanometers big (a few
billionths of a meter wide) and can catch a moment in time to reveal what happens over about 15 nanoseconds (15
billionths of a
second long).
