    • A measuring apparatus includes: laser sources (2a, 2b); and a control unit (19) for outputting an excitation start signal (20a, 20b) that instructs the laser light sources to start excitation, and outputting an oscillation start signal (21a, 21b) 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 (2a) and a second laser source (2b) 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 (10) sets timing to output the excitation start signal to the first laser sourc 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.
    • 测量装置包括:激光源(2a,2b); 以及控制单元(19),用于输出指示激光源开始激励的激励开始信号(20a,20b),并输出振荡开始信号(21a,21b),以指示激光光源在a 从激励开始信号的输出经过预定时间,从而产生来自激光光源的脉冲光。 激光源包括第一激光源(2a)和第二激光源(2b),其中从激发开始到产生脉冲光的准备时间比第一激光源的制造时间长。 控制单元(10)根据第一激光源和第二激光源之间的准备时间的差,设置定时以将激励开始信号输出到第一激光源以跟随定时以将激励开始信号输出到第二激光源。
