Abstract: The light output of a doubly pulsed laser is monitored by converting the two successive light pulses into corresponding electrical pulses and feeding the electrical pulses to a pair of parallel connected circuit channels. A first one of the circuit channels is conditioned to receive the first electrical pulse while a second one of the circuit channels is rendered immune to that pulse. The first electrical pulse charges a capacitor to a voltage proportional to the pulse amplitude and the voltage is displayed on a direct current voltmeter. The second circuit channel is conditioned to receive the second electrical pulse while the first circuit channel is rendered immune to that pulse. The second electrical pulse charges another capacitor to a voltage proportional to the pulse amplitude and the voltage is displayed on another meter. Both voltages are maintained for comparison with one another, after which the circuit channels may be reset to their initial condition for reception of the next set of electrical pulses.

Abstract translation: 通过将两个连续的光脉冲转换成相应的电脉冲并将电脉冲馈送到一对并联的电路通道来监测双脉冲激光器的光输出。 电路通道中的第一个被调节以接收第一电脉冲，而电路通道中的第二个电路通道被免除该脉冲。 第一个电脉冲将电容器充电到与脉冲幅度成比例的电压，并且电压显示在直流电压表上。 第二电路通道被调节为接收第二电脉冲，同时使第一电路通道免于该脉冲。 第二个电脉冲将另一个电容器充电到与脉冲幅度成比例的电压，并且电压显示在另一个仪表上。 维持两个电压以便彼此比较，之后电路通道可以被重置到其初始状态以接收下一组电脉冲。
