We study theoretically the recently proposed hole spin initialization schemefor $p$-doped quantum well or dot systems via coupling to trion states withsub-picosecond circularly polarized laser pulses. We analyze the efficiency ofspin initialization an predict the intrinsic spin coherence loss due to thepulse excitation itself as well as the phonon-induced spin dephasing, bothtaking place on the timescale of the driving laser pulse. We show that theratio of the degree of dephasing to the achieved orientation effect does notdepend on the pulse area but is sensitive to the temperature and detuning. Theoptimal excitation parameters are identified.
