We have numerically and experimentally investigated the characteristics of the optical parametric chirped-pulse amplification (OPCPA) of femtosecond Ti:sapphire laser pulses by using BBO crystals. Numerical calculations showed that a high gain and a broad gain bandwidth could be obtained with a 532-nm pump laser. The dependence of the gain profile of OPA on phase matching angles, pump intensity, and crystal length was numerically investigated. Experimental results showed that the broadband amplification of femtosecond Ti:sapphire laser pulses could be realized by OPCPA and that the temporal fluctuation of a pump laser resulted in the modulation of amplified spectra in OPCPA.
