Abstract
A beam deflection system includes 2M laser light sources configured to emit laser lights, each laser light source being configured to switch two different center wavelengths to each other. The 2M laser light sources are divided into two sets of M types. The laser lights emitted from the two sets of M types of laser light sources are combined and input to a beam deflector. When (i) N is defined as an integer satisfying an expression of '1≤N≤M', and (ii) center wavelengths of Nth laser light sources of the two sets of M laser light sources are defined as λN and λM+N, an expression of “λ1< . . . <λN< . . . <λM<λM+1< . . . <λM+N< . . . <λ2M” is satisfied.
