Abstract

Photodynamic therapy (PDT) treatment is a new treatment for tumour and Dermatology. With the successful development of the second-generation photosensitizer and the significant manifestations in clinics, PDT has shown a more extensive application potentials. To activate the photosensitizer, in this paper, we present a GaAs-based diode laser system with a wavelength of 635 nm. In this system, to prolong the working life-time of the diode lasers, we use specific feedback algorithm to control the current and the temperature of the diode laser with high precision. The clinic results show an excellent effect in the treatment of Condyloma combined with 5-ALA.
