摘要： A system for detecting energy leakage from an optical fiber transmitting high power laser beams. A second optical fiber is placed together with the laser power transmitting fiber into a jacketing tube or conduit. The second fiber is connected at one end to a light source and at the other end to a photosensitive diode. Leakage of laser energy from the power transmitting fiber will cause a failure of the second optical fiber, reducing or terminating the transmission of light to the photosensitive diode. Energy leakage from the laser power transmitting fiber can therefore be detected by monitoring the output of the photosensitive diode.

摘要： A method for single sided laser shock peening an article includes laser shock peening a laser shock peening surface on a first side of the article while maintaining an opposite second surface on a back side of the article in acoustic communication with a shock attenuating material. The second surface is opposite the laser shock peening surface. The shock attenuating material is a material that does not allow tensile waves to be reflected back off the back side through the article. The shock attenuating material may be a liquid metal and the article made from a titanium alloy. One such article is a gas turbine engine airfoil of an integrally bladed disk and the surfaces may be on an edge of the airfoil. The shock attenuating material may be one that dissipates compressive waves or reflects back compressive shock waves caused by the laser shock peening.
摘要翻译：用于单面激光冲击硬化物品的方法包括在制品的第一侧上激光冲击硬化激光冲击硬化表面，同时保持与冲击衰减材料声学连通的制品背面上的相对的第二表面。第二个表面与激光冲击喷丸表面相对。冲击衰减材料是不允许拉伸波从背面反射穿过物品的材料。冲击衰减材料可以是液态金属，并且由钛合金制成的制品。一个这样的物品是整体叶片盘的燃气涡轮发动机翼型，并且表面可以在翼型的边缘上。冲击衰减材料可以是消除压缩波或反射由激光冲击喷丸引起的压缩冲击波的材料。
