We have experimentally observed the dynamics of laser outputs in a microchip laser with frequency-modulated feedback light. We have observed rich dynamics that can be interpreted as three types of dynamics at different frequencies: (1) periodic bursts at twice of the frequency of the modulation of the external mirror, (2) chaotic pulsations at the relaxation oscillation frequency, and (3) clusters at the instantaneous Doppler-shifted frequency. We have confirmed these rich dynamics by using numerical simulations.
