Paper Abstract

For the application of photodynamic therapy (PDT) for wider lesions of early gastric cancer we employed a new model of an excimer dye laser (EDL), because it is necessary to increase the average output for the irradiation of enough energy to the wider lesion within a limited time, in addition to protecting the single quartz fiber from destruction. The characteristics of the new laser are as follows: wavelength, 630 nm; pulse energy, 4 mJ; peak power, 400 kW; pulse width, 10 nsec; frequency of repetition, 80 Hz; average output, 320 mW. The PDT can be applicable for wider lesions of early gastric cancer by employing the new model of EDL, that can produce the average output of 320 mW with repetition of 4 mJ in 80 times per second.
