We report the first observation of transverse magnetic hole focusing in high quality two-dimensional hole systems confined in square and triangular quantum wells grown on (311)A GaAs substrates. The results demonstrate ballistic hole transport over distances up to 11 μm and allow us to probe the constant energy contours in k-space for these two types of confinement.
