A versatile, highhyphen;speed multichannel counter, which has maximum temporal resolution Dgr;t=30 ns and channel length up to 4095, has been developed for various kinds of timehyphen;resolved laser spectroscopic measurements. High speed, large counting capacity, low cost for fabrication, and ease of circuit assembly have been accomplished by introducing both parallel and pipehyphen;line processing. The performance of this system has been verified in the applications to cw laser radar, timehyphen;ofhyphen;flight measurement of molecular beam, and radiative lifetime measurement.
