We experimentally study the transverse distribution of intensity noise in the far field of a single-mode semiconductor laser. We show that a large amount of noise is present in the higher-order nonlasing transverse modes (parallel to the diode junction). Furthermore, correlations between the TE<sub>00</sub> and the TE<sub>10</sub> modes are observed.
