摘要：
The present invention provides a multiple wavelength excitation light source characterized in the provision of an optical multiplexing element that has a plurality of input terminals connected to lasers and functions to multiplex a plurality of lights that have different characteristics; and a reflecting element inserted near the output side of the output terminal of the optical multiplexing element, and functioning to reflect the light multiplexed at the optical multiplexing element at a low reflection coefficient. Accordingly, it becomes possible to provide high output excitation light in a stable manner.
