TIPTOE
General description of TIPTOE
TIPTOE is an acronym for Tunneling Ionization with a Perturbation for the Time-Domain Observation of an Electric field. TIPTOE is a pulse characterization technique in which the extreme nonlinearity of ionization is utilized.
An input laser pulse is split into two pulses, one strong and the other weak. The two laser pulses are focused on a target (typically, air), and ionization yield is measured as a function of time delay between the two pulses. The temporal profile of the input pulse can be found from the modulation of the ionization yield using an appropriate reconstruction algorithm.
Since the TIPTOE method utilizes the extreme nonlinearity of ionization, the technique can be applied in a broad wavelength range. According to computer simulations calculated by solving time-dependent Schrodinger equation, the TIPTOE technique can be applied for a wavelength range longer than 200 nm (and up to 20µm in practice).
The TIPTOE technique can be applied for single-cycle, few-cycle and multi-cycle pulses. The intensity of the input pulse should be high enough to ionize the target.
