In a master oscillator power amplifier system a powerful train of pulses can be generated. A simple method is described to measure the duration of these pulses. The measurements have been performed both at the fundamental frequency (1053 nm) and at the second harmonic (527 nm). In accordance with theoretical expectations we have observed a narrowing of the pulse owing to frequency doubling.
