A novel super-continuous spectrum light source system possessing same-phase high-power single-wavelength semiconductor lasers comprises a same-source multi-path clock (1), a super-continuous spectrum light source (2), and a plurality of single-wavelength semiconductor lasers (3). The frequency of each single-wavelength semiconductor laser is adjusted to integer times or division times of the frequency of the super-continuous spectrum light source (2) by using the same-source multi-path clock (2). The weakness that the super-continuous spectrum light source (2) is difficult to cover wavelengths less than 400 nm and the power density at the wavelength of 400-2400 nm is less than 10 mw/nm are compensated by using single-wavelength semiconductor lasers. The wavelength of the single-wavelength semiconductor lasers (3) can cover 375-2400 nm, and the highest power density can reach 200 mW/nm, so that a composed novel super-continuous spectrum light source is applicable to the fields such as spectral microscopy in a range of 375-400 nm. In addition, through clock control on the single-wavelength semiconductor lasers (3) and a pulse generation circuit of the super-continuous spectrum light source (2), same-phase output of the single-wavelength semiconductor lasers (3) and the super-continuous spectrum light source (2) can be kept, and opposite pulse delays are flexible and adjustable.
