HCXtreme Optical Fiber for High Powers in Tight Bends

From OFS Specialty Photonics Division
 

 
Silica optical fibers are being increasingly used for delivering laser power in various medical applications. Laser damage to the optical fiber can occur when fiber is bent while transmitting high power laser light, leading to a serious concern for medical application. In many medical applications, small radius bend of the fiber is often required. In this study, we examined the damage of step index multimode fibers transmitting Ho:YAG laser power at wavelength of 2140 nm when bent to a radius down to 5 mm and carried an average power of up to 100W. We compared the results of different types of fiber and fibers made with different manufacture processes in an attempt to gain more knowledge about the failure mechanism. Other relevant issues are also discussed.
