Abstract
Typically, output from high power, diode lasers and arrays must be transported to a final application/treatment site, whether the application is industrial, military or medical. Many demands are placed on optical fibers to couple the laser output into their structures and to transmit the power to the application site. All silica fibers become much more expensive as the diameter of the fiber increases to handle larger spot sizes and higher NA beams, especially from diode arrays. High strength, low fatigue Hard Plastic Clad Silica fibers provide benefits of larger Numerical Aperture (NA), more flexibility and less strain at the core-clad interface. Fibers with these characteristics and available in both high OH and low OH versions for UV and NIR spectral regions are described. Short and long term strength, and spectral properties are presented. Results for a new high NA version are also presented.
