摘要：
A pulsed layer spectrometer was developed using a tunable He-Ar high-pressure laser. The accuracy of synchronizing the laser with an object being investigated was about 1 nsec. In order to automate the measurements, pulse voltmeters having a wide dynamic range and devices for analog processing of the signals were developed. The spectrometer was used to study the characteristics of the 2p//1//0-1s//5 transition in argon, in a nanosecond electric-discharge plasma. Measurements were made of the time dependence of the gain at the center of the transition and of the collisional broadening due to the helium (19 GHz/atm).
