The sequentially timed all-optical mapping photography (STAMP) is known for a transient imaging method with a femtosecond temporal resolution. In this study, we propose a compact and low-cost fiber-based laser source for the STAMP method. Multi-wavelength CW lasers are modulated by a Mach-Zehnder modulator for generating multi-wavelength optical pulses. The pulse interval is controlled by a wavelength interval of the CW lasers and an optical fiber length.
