Paper Abstract

The Applied Optronics Corporation's model LM-400 is the first commercially available visible diode laser system which can meet the light source requirements for photodynamic therapy (PDT). PDT is a treatment for cancer which uses the topical illumination by a precise wavelength of light to photochemically activate an otherwise nontoxic drug, resulting in the localized necrosis of cancerous cells. Following a discussion of the light source requirements for PDT, we describe the system design and performance of AOC's self-contained, all solid- state, visible diode laser system. When compared to dye laser systems pumped by secondary lasers, diode laser systems offer significant advantages in terms of cost, simplicity of operation, portability, and negligible installation and maintenance requirements.
