      abstract     = {Femtosecond laser pulses enable the synthesis of light
                      across the electromagnetic spectrum and provide access to
                      ultrafast phenomena in physics, biology, and chemistry.
                      Chip-integration of femtosecond technology could
                      revolutionize applications such as point-of-care
                      diagnostics, bio-medical imaging, portable chemical sensing,
                      or autonomous navigation. However, current sources lack the
                      required power, and the on-chip amplification of femtosecond
                      pulses is an unresolved challenge. Here, addressing this
                      challenge, we report >50-fold amplification of 1~GHz
                      repetition-rate chirped femtosecond pulses in a
                      CMOS-compatible photonic chip to 800 W peak power with 116
                      fs pulse duration. Nonlinear effects, usually a hallmark of
                      integrated photonics but prohibitive to pulse amplification
                      are mitigated through all-normal dispersion, large mode-area
                      rare-earth-doped gain waveguides. These results offer a
                      pathway to chip-integrated femtosecond technology with
                      power-levels characteristic of table-top sources.},
