PROBLEM TO BE SOLVED: To provide a phase compensation system which compensates a phase shift of repetition frequency in the repetition frequency synchronization of two mode-locked pulse laser sources, and to provide a laser scanning microscope system. SOLUTION: The phase compensation system 413 contains two mode-locked pulse laser sources 401 and a laser synchronization device 402 that synchronizes the repetition frequency or cycle of the laser sources. Further, the system is equipped with a detection device 410 which detects the repetition frequency or cycle of the two mode-locked pulse laser sources 401, a phase delaying optical system 411 which varies the phase of the repetition frequency or cycle of laser rays emitted from, at least, one of the two mode-locked pulse laser sources 401, and a drive mechanism 412 which drives the phase delaying optical system 411 to keep the phase of the repetition frequency or cycle of the two mode-locked pulse laser sources 401 constant on the basis of signals obtained through the detection device 410.
