I could write 1 femtosecond as "1 femtosecond" : not a zero in sight. or as 0.000001 nanoseconds (6 zeros) or .000001 nanoseconds (5 zeros) 1 fs = 10-15 seconds so there are 14 0s between the decimal point and the 1.
There are 10-15 seconds in a femtosecond.
If with less you intend "dealing with smallest dimensions" femtosecond lasers exist, emitting pulses whose duration is one billion part of a microsecond.
A femtosecond is one billionth of one millionth of a second.
Examples: -- picosecond -- femtosecond -- yoctosecond -- attosecond
I'm tempted to reply ½ a pecosecond(!) However, I think you're asking what is the next description below pecosecond; it is a femtosecond (10−15 second). There are 1000 femtoseconds in a pecosecond.

A femtosecond is 1000th of a picosecond.
The definition of the word femtosecond is basically it's a SI united of time equal to 10 to 15 seconds. It is approximately equal to one quadrillionth of a second.
