We present a novel ultrafast multipass laser amplifier design optimized for sub-millijoule output energy and capable of being operated at repetition rates exceeding 40 kHz. This ti:sapphire based system makes use of a grism based stretcher, a cryogenically cooled ti:sapphire crystal and an astigmatically compensated multipass amplifier design that allows for pumping with significantly lower pump pulse energies than has been demonstrated to date. We also make use of the downchirped pulse amplification scheme to minimize loss in the pulse compression process. Preliminary experiments demonstrate an output pulse energy of 290 muJ at 10 kHz and 270 muJ at 15 kHz with a pulse duration of 36 fs.
