a The laser’s temporal profile measured with a sequoia third-order autocorrelator (Sequoia HD, Amplitude Tech.). b The measured (white) and simulated (red) profiles of the focal intensity, overlayed over an x100 magnification image of the focus taken at low-power, with the same scale as the r axis. c The measured (black) and simulated (red) profiles of the laser pulse duration. The measured trace was obtained using a 2nd order autocorrelator.
