Pulse-timing effects in the far field of a passively Q -switched microchip laser that are caused by the changing cavity mode during pulse emission are described. Measurements are performed on a passively Q -switched Nd:YAG laser that produces 3-ns pulses, and delays in pulse arrival times of up to ~270 ps are observed between the center and the off-axis position. The measured data agree well with a simple analytical model. Pulse delays of this order are important, for instance, in high-precision range-finding applications.
