1. A light source system comprising:
a first light source device including a first laser light source and configured to emit first light having a first wavelength;
a second light source device including a second laser light source and configured to emit second light having a second wavelength which is a longer wavelength than the first wavelength;
a splitting unit configured to split the first light emitted from the first light source device into third light having a third wavelength which is a same wavelength as the first wavelength and fourth light having a fourth wavelength which is the same wavelength as the first wavelength;
a wavelength converter configured to be excited by the third light to emit fifth light having a luminescence peak at a fifth wavelength between the third wavelength and the second wavelength;
a combining optical system configured to combine the second light, the fourth light, and the fifth light together; and
a control device configured to control a light output of the second light source device and a split ratio between the third light and the fourth light in the splitting unit.
