ABSTRACT:
High power transmission in the 2.6 .mu.m to 16 .mu.m infrared region is hampered by damage to the ends of the optical fiber, especially the delivery end, which greatly limits the delivery capacity of the optical fiber. The threshold for damage experienced by the ends of an optical fiber, particularly at the delivery end, is raised by destroying the naturally formed speckle pattern present in a normal fiber optic laser delivery system. The speckle pattern is destroyed by vibrating the laser, the receiving end of the optical fiber, or an optical element along the transmission path. The system comprises a laser source for infrared emissions, an optical fiber capable of transmitting said wavelengths, and a vibratory device such as an ultrasonic transducer. The vibratory device is used to vibrate the laser, the optical fiber, or another optical component in the transmission path. This system not only transmits higher power densities in the infrared region but also delivers the power more evenly distributed power.
