Abstract

See full text

A measuring apparatus includes: laser sources; and a control unit for outputting an excitation start signal that instructs the laser light sources to start excitation, and outputting an oscillation start signal to instruct the laser light sources to start oscillation after a predetermined time has elapsed from the output of the excitation start signal, so as to generate pulsed light from the laser light sources. The laser sources include a first laser source and a second laser source of which preparation time from the start of the excitation to the generation of the pulsed light is longer than that of the first laser source. The control unit sets timing to output the excitation start signal to the first laser source to follow timing to output the excitation start signal to the second laser source according to a difference of the preparation time between the first and second laser sources.
