摘要： A laser light amplification system that amplifies a laser beam emitted from a source as low-amplification seed laser light signal. The low-amplification seed laser light signal is amplified by stimulating emissions of the population inversion provided by a pumping diode to generate an amplified laser light signal. Amplified laser light signal is directed to an object undergoing laser ultrasound testing. Amplified laser light is scattered by the sound energy wave about the object. Scattered laser light is collected by an interferometer and used to detect and characterize acoustic energy. The present invention provides higher pulse rates, improved pointing stability, and optionally variable pulse rates for a variety of uses, including for non-destructive laser ultrasonic testing of materials.

摘要： A photoreceiver assembly separates low level, high frequency signals from a large, low frequency pulse. The photoreceiver assembly extracts high frequency ultrasonic signal from the optical frequency of light by shining an ultrasonic base band signal onto a photodetector for conversion into an electrical signal in the bandwidth of interest. A photodetector is coupled to a splitter, which is coupled to a plurality of transimpedance signal paths. In operation, the splitter receives a current from the photodetector, separates, and directs the current to transimpedance signal paths. The photoreceiver further includes a transimpedance amplifier assembly coupled to the transimpedance signal paths. The transimpedance amplifier assembly converts the high frequency component of the current into a signal voltage that defines an ultrasonic signal. The transimpedance amplifier assembly includes a forward path gain arrangement for accommodating the electrical configuration of the splitter.

摘要： A lasing system for forming a sealed barrier between a process environment and an environment external to the process environment. The lasing system includes a wall enclosing the process environment. The lasing system also includes a laser connector coupled to the wall and a line. It should also be added that in one exemplary embodiment, the laser connector is configured to be releasably coupled to the wall and the line. The line, such as for example a fiber optic line, provides the lasing system with laser energy from a high-powered laser. In one exemplary embodiment, the energy from the laser is between 100 to about 1000 watts. Operatively, the wall and the laser connector form an environmental barrier between the process environment and the outside environment.

摘要： The invention is directed to a laser ultrasound testing system with adaptive generation of sonic energy signals. The system may detect or test features of the manufactured object such as defects and layer properties. A laser generator initiates a sonic energy signal in a manufactured object. A measuring device measures the sonic energysignal. Then, a signal analyzer and/or a model processor determine if the signal is optimized. If the signal is not optimized, optimized operating characteristics of the laser generator are calculated. These optimized operating characteristics may include wavelength, beam dimension, temporal profile and power. Next, the laser generator initiates an improved sonic energy signal by utilizing the optimized operating characteristics. In this manner, more accurate testing and detection is achieved.

摘要： A wave characteristic adjusting device can compensate for distortion caused by the scanning motion of a probe beam of a two-wave mixing interferometer in a rapid scanning laser ultrasound testing device. In such a device, a laser pulse directed at periodic points along a path across the surface of an object initiates an ultrasonic signal. An interferometer measures this ultrasonic signal by scanning a pulsed probe beam along a similar path directed at the object in the vicinity of the initiating laser pulse. However, the probe beam pulse may exhibit a Doppler shift causing a loss in sensitivity of the two-wave mixing interferometer. The wave characteristic adjusting device compensates for this Doppler shift, thereby improving the sensitivity of the two-wave mixing interferometer.
