CIRCULARLY POLARIZED SOLITON GENERATING DEVICE AND MULTIPHOTON MICROSCOPIC IMAGING SYSTEM

A circularly polarized soliton generating device (1) and a multiphoton microscopic imaging system (10). The circularly polarized soliton generating device (1) comprises a pump laser (11), a first quarter-wave plate (12), a first focusing lens (13), and an optical fiber (14) arranged on a same optical path, where a linearly polarized light generated by the pump laser (11) is converted into a circularly polarized light via the first quarter-wave plate (12), the circularly polarized light is coupled into the optical fiber (14) via the first focusing lens (13), and the circularly polarized light is converted into a circularly polarized soliton via the optical fiber (14). The linearly polarized light is converted into the circularly polarize light via the first quarter-wave plate (12), and then the circularly polarized light is converted into the circularly polarized soliton via the optical fiber (14). Under same conditions, the energy of a circularly polarized soliton is 1.56 times of the energy of a linearly pol
