Time-resolved spectroscopy techniques are the most powerful tools in the research of the ultrafast phenomena. Optical Multichannel Analyzer (OMA) is often used in such spectra's measurement. In the old product of OMA, OMA II, its console runs too slow to cope with the large quantity of data in the experiments, and its limited functions and unexpansibility lead to much inconvenience in using. A parallel interface is made to realize the communication between the controller and the lab computer so that the OMA console can be replaced by the computer. Clearly the computer has much higher rate to process the date and much larger media to store data. Furthermore, the computer can control the other devices such as a shutter, a step motor for delay line and so on. Also the method of data process can be changed according to the different experiments by program. In one word, it is the most important that the computer can be used to control the entire course of the experiments and do some necessary real-time process. A femtosecond time-resolved absorption apparatus based on OMA II and a 386 computer is established and a control software for DOS is developed.
