We present a kHz-rate all-solid-state Ti:sapphire oscillator–amplifier system producing 1.8 mJ sub-20 fs pulses using a single multipass amplifier stage pumped by ≈10 mJ pulses. Compensation for gain narrowing and high-order dispersion is provided by chirped dielectric multilayer optics. The focused peak intensity approaches 1018 W/cm2, making this compact high-repetition-rate source attractive for a wide range of high-field applications.
