Cyclotron resonance at the microwave frequency is used to measure the band edge mass (m{sub b}) in the two-dimensional hole (2DH) system, confined in 30 nm quantum wells in the Al{sub 0.1}Ga{sub 0.9}As/GaAs/Al{sub 0.1}Ga{sub 0.9}As heterostructures. We find that for 2DH density p {le} 1.0 x 10{sup 10} cm{sup -2}, m{sub b} is nearly constant, {approx}0.35m{sub e}. It increases with increasing density, to {approx}0.5m{sub e} at p = 7.4 x 10{sup 10} cm{sup -2}.
