Limitations imposed on the saturation energy of high-power slab-coupled optical waveguide amplifiers were studied for pulsed signal transmission. Loss due to the two-photon absorption and free-carrier absorption processes becomes a dominant factor for ultrashort-pulse amplification, leading to lower saturation energy. TPA and FCA coefficients are measured to be 65 cm/GW and 7times10[superscript -17] cm[superscript 2], respectively. Carrier-related gain recovery times vary from 160 ps to 380 ps at bias currents from 4 A to 1 A, respectively.
