| titleOfInvention | Preamplifier for detection laser in laser ultrasonic inspection system |
| abstract | A pulse detection laser is provided. The pulse detection laser includes a single frequency oscillator, a continuous preamplifier, and a pulsed amplifier. A single frequency oscillator generates a seed laser beam and is optically connected to a continuous preamplifier. A continuous preamplifier amplifies the seed laser to produce an intermediate power laser beam. A pulsed amplifier optically connected to the continuous preamplifier receives the intermediate power laser beam and amplifies the intermediate power laser beam to generate a pulse detection laser beam. One role of this pulse detection laser is to illuminate the ultrasonic displacement. The light from the laser is scattered, collected and analyzed using an interferometer to demodulate the ultrasonic displacement caused by the ultrasonic return echo at the surface of the component. |
