We study a pulse stacking at an external cavity for the enhancement of peak power, where the pulses are generated at the IR-FEL oscillator at LEBRA facility, Nihon U. Advantages of the accelerator based IR light source include a high peak power, a few cycles short pulse width, and a high repetition rate over MHz, that have a great potential to boost the attosecond science area through the high-harmonic generation with a noble gas target. We started constructing the external cavity with an IR mode-locked fiber laser, since the LEBRA-FEL lasing is too short for the tuning of external cavity. We report the present status of the external cavity construction, and make comments for the further developments.
