摘要： A workpiece (1) is subjected to laser shock peening by the application of a series of high power pulses of a laser beam (2). When incident upon a target area (3) of the surface of the workpiece (1), a plasma (4) is generated. The rapid expansion of the plasma (4) applies a pressure (5) to the workpiece (1). According to the present invention, gas is applied to the target area in order to produce a region of gas (7) having a higher pressure than the ambient environment, thereby confining the plasma (4). Advantageously, this may remove the need for a liquid confinement medium (6). In this embodiment, there is an optional ablative layer (15) disposed on the surface of the workpiece (1).

摘要： A laser shock peening device and components thereof. The optical system of the laser peening device includes sapphire optical elements (318), such as a lens (318b) or a prism (318a). A water channel (322) is provided in a pen (206) for the laser shock peening device that has a curved flow path to direct the water. An air conduit (400) in the pen (206) provides a stream of air to the surface receiving the laser shock peening treatment.

摘要： A system (100) and device for laser shock peening device and components thereof. The system (100) includes umbilical cords (112) with flexible outer sheaths (120a, 120b) surrounding the fiber optic cable within the umbilical. The umbilical may include two different sections (112a, 112b) with different outer sheathes (120a, 120b). The applicator device (102) may have a laser peeing pen (406) that has a longitudinal axis (A2-A2) that is spaced from the longitudinal axis (A1-A1) of the applicator device (102). In a method of operating the device, a first step (500a) includes a vertical movement, followed by a second step (500b) of rotation movement, and then another step of vertical movement (500c) opposite the first step.

摘要： A system (100) for performing a laser peening application on a workpiece. A purge system (112) is included with the system to provide a compartment (300) housing combustion sources with compressed air so that the compartment (300) has an increased air pressure. Also, a method of operating the system (200) in which power is provided to the system, but only the purge system operates initially. Only after the purge system (112) has been operating, are the other subsystems and components of the system (100), like the laser, provided with operational power.
