ABSTRACT:
A tissue photoradiation system uses a hematoporphyrin or hematoporphyrin derivative dye in tissue to be irradiated and arranges a xenon ion laser 10 for simultaneous lasing. Deep blue light is produced at wavelengths of about 406-427 nanometers and red light at a wavelength of about 627 nanometers by using partially transmitting mirrors 12 and 13 arranged at opposite ends of the laser resonator. Mirror 12 has a coating 14 that substantially reflects blue light and partially transmits red light to produce a red light output, and the coating 15 of mirror 13 substantially reflects red light and partially transmits blue light producing a blue light output. The blue light output is transmitted to a diagnostic tissue irradiator 21 to illuminate the tissue and diagnose its condition. A transmission system using an optical fiber 25 delivers the red light to the tissue for treatment purposes. The red light is radiated out the side of an optical fiber region 30a to be directed into large area of tissue.
