We demonstrate an extension of forming a photorefractive volume grating in an Fe:LiNbO₃ crystal by chirped intense femtosecond laser pulses generated from a Ti:Al₂O₃ regenerative amplifier at 1 kHz. We confirm that one-photon absorption is still dominant in the Fe:LiNbO₃ crystal up to 70 GW/cm². To generate a photorefractive grating at such a low laser repetition rate within a practical writing time, the laser pulse intensity is increased to >30 GW/cm². Furthermore, we demonstrate the amplification of femtosecond laser pulses by the chirped volume grating that is written in the Fe:LiNbO₃ by two-wave mixing.
