Effective delivery of the activation light for photodynamic therapy (PDT) of internal organs is a challenge. In this paper, we present a direct de-ionized water-cooling semiconductor laser package design for PDT of esophageal carcinomas. This self-sustained photonic light delivery system is designed to provide the correct amount of light dose for optimal treatment. The direct de-ionized water-cooling technique discussed in this paper not only removes heat efficiently but also results in a high optical power output. Voltage-current and power-current characteristics, and near field optical patterns for unidirectional and direct de-ionized water-cooling, are used to show the validity of the technique. Modeling of fluid flow is conducted to investigate the effect of flowing water over the laser package.
