Attosecond pulses are produced in a process called high-order harmonic generation, in which a short, intense laser pulse interacts with atoms or molecules in a highly nonlinear process, leading to the generation of high-order frequencies of the fundamental laser with a large spectral bandwidth, supporting pulses with attosecond duration.

Marcus Dahlstr om Attosecond time-delays in photoionisation attosecond time scale, the most fundamental of which is quantum tunneling. The tunneling process initiates a range of strong ﬁ eld phenomena such as high harmonic generation (HHG), We study photoemission, the process where electromagnetic radiation interacts with matter and leads to the emission of electrons. This process takes place on an incredibly short time scale, but with the aid of advanced laser technology we can study its dynamics and the quantum mechanical rules that govern it. Here, we study the photoionization of helium with a 3D momentum spectrometer.

Each session focuses on one aspect of attosecond science and consists of one keynote lecture in addition to three progress reports from early career researchers. A stopwatch with attosecond accuracy "An attosecond is the billionth part of a billionth of a second, or in other words, an attosecond is to a second as a second is to the age of the universe," says Reinhard Kienberger, professor of laser and X-ray physics at the TU Munich. 12 attoseconds is the world record for shortest controllable time. by Max Born Institute.

Also, explore tools to convert attosecond or millennium to other time units or learn more about time conversions. However, such applications for high precision time domain measurement, especially state of the art attosecond time resolved measurement, is less explored despite its great significance.

An ultrashort laser pulse is comprised of a few of 0= 1. Hamiltonian for interaction with eld and ion: H = H. V+ V. A. Kinetic energy of electron in a uniform electromagnetic eld: H. V= 1 2 [^p + A(t)]2. Vector potential of both attopulses and laser elds: A(t) = A. X(t) + A. L(t) Argon potential within single-active electron approximation: V. An attosecond is 1×10 −18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. Atto-was derived from the Danish word for eighteen (atten).
