Abstract

Accurate knowledge of the intensity of focused ultrashort laser pulses is crucial to the correct interpretation of experimental results in strong-field physics. We have developed a technique to measure laser intensities approaching $10^{15} W / {cm}^{2}$ with an accuracy of 1 $%$ . This accuracy is achieved by comparing experimental photoelectron yields from atomic hydrogen with predictions from exact numerical solutions of the three-dimensional time-dependent Schrödinger equation. Our method can be extended to relativistic intensities and to the use of other atomic species.
