Abstract
According to the progress of optical reaction materials and so on, various laser flash photolysis systems
have been developed. In the photolysis, a xenon lamp with high flashing intensity is used as a reference
light source. However, a flashing jitter inherent in the xenon lamp has a harmful influence on the
measurement accuracy. In detail, flashing light of a nanosecond laser dose not coincide with that of the
xenon lamp so often. In order to overcome the above issue, a xenon flashing circuit such that generates
lamp intensity with flat region is proposed. This paper shows the proposed flashing circuit having a LC
cascade circuit with trimming components between DC voltage source and the xenon lamp. By using
this circuit, the xenon light intensity with the flat region more than 20 μs is realized and it is shown that
its feature contributes the research of the photolysis.
