Paper Abstract

We present an electrical pump optical probe experiment to investigate the temporal and spectral gain dynamics of an actively modelocked diode laser. The temporal behavior of the gain is studied with picosecond time resolution by measuring the transmission of a modelocked Ti:sapphire laser synchronized to the semiconductor laser through the active region of the diode. Our results show that the gain transients exhibit a strong temporal asymmetry which leads to incomplete modelocking.
