Single isolated attosecond pulse is a new powerful tool for studying dynamics of correlated electron motion in pump-probe experiments [1]. Such pulses, as short as 67 attoseconds, can now be generated with the Double Optical Gating (DOG) method. The broadband XUV supercontinuum spectrum of the isolated attosecond pulse is particularly suitable for probing the time variation of the electronic states...
Generalized Double Optical Gating is an effective scheme for generating single isolated attosecond pulses with multi-cycle driving lasers. It is to be implemented using a >100 mJ Ti:Sapphire laser to upscale the attosecond photon flux.
First experimental measurement of ellipticity dependence of high harmonics produced from 400 nm driving pulses is reported and compared with harmonics produced from 800 nm driving pulses in an argon filled gas cell.
Using a generalized version of double optical gating, we produced single isolated attosecond pulses with 2 mJ, 25 fs driving lasers. Through attosecond streaking, we characterized isolated 160 attosecond pulses with 170 pJ pulse energy.
