Ultrashort optical pulses enable us to observe many fascinating dynamics in proteins. In this review, we will first illustrate the progress of laser technology and then describe application of the laser pulses to observation of ultrafast protein dynamics. Developments of laser technology for the ultrashort pulse generation significantly improved the time-resolution of the measurements. The developments also allow us to observe vibrational and electronic coherence of proteins, which provides greatly increased understanding of protein dynamics.
