Fiber Optic Delivery of Multi-Pulsed Laser Source for Tone Burst and Phased Array Ultrasonic Excitation

The purpose of this program is to modify our existing narrow-band system for pulsed generation of laser ultrasound so that it can be delivered by fiber. This allows the narrow-band source system to be manipulated and used in direct measurement applications outside of the research laboratory. These applications include use in a hybrid laser generation/ EMAT detection system for defect detection.

Pulsed Nd:YAG laser array, developed by Todd Murray, is coupled for narrow-band fiber delivery
