TLDR
In this paper, an irradiation attachment for an optical fiber which provides an output of light that has a highly uniform intensity is described. But the device is not suitable for photodynamic therapy.Abstract:
An irradiation attachment for an optical fiber (4) which provides an output of light that has a highly uniform intensity. The device includes a hollow spherical shell (1) having a diffusive reflective surface or target (11) supported (12) therein. Light is directed into the hollow spherical shell (1) so that it reflects off the diffusive reflective surface or target (11). The reflected light is internally reflected off the inner surface of the hollow spherical shell (1) several times before passing through an output aperture (8). As a result of the internal reflection within the hollow spherical shell (1), the light leaving the device has a highly uniform intensity. The device is particularly useful for photodynamic therapy.read more

Surgical laser system with multiple output devices
TL;DR: A surgical laser system includes a laser, interchangeable peripheral output devices, a sensor effective to sense the power output of a peripheral device coupled to the sensor, and a control circuit for calibrating the radiation output of each device, interlocking the system to prevent use of a device before it has been calibrated, and controlling the production of calibration, aiming and main power laser beams as mentioned in this paper.
Patent
Intracavity laser phototherapy method
TL;DR: In this paper, a method for uniform irradiation of the inner wall of a hollow organ is described, including the steps of inserting a catheter having a deflated translucent balloon into the interior of the organ, inflating the balloon until it forms a predetermined configuration and distends the inner walls of the organs to be irradiated into a contiguous and congruent configuration, and transmitting light through the fiber out the tip whereby light of uniform intensity irradiates the wall.
