摘要：
A laser light source (10) has semiconductor lasers (1) and a waveguide tube (3) for propagating emission light from each of the semiconductor lasers (1). The semiconductor lasers are arranged on the upper end on the incident surface (31) side of the waveguide tube such that the emission light (4) from each of the semiconductor lasers enters into the waveguide tube from one end surface (31) of the waveguide tube and exits from the other end surface (32) of the waveguide tube. The structure can realize a small-sized laser light source having high output and capable of outputting emission light having uniform emission light intensity distribution.
