Paper Abstract
We demonstrate the design of a fiber optic beam delivery system for particle image velocimetry (PIV) applications. The system is capable of transmitting pulse energies of about 10 mJ in 7 ns pulses from a frequency doubled and Q-switched Nd:YAG laser; it is hence suitable for use with high speed air flows. The fiber used has a fused silica core of diameter 400 micrometers , and is of the step index multimode type. The output beam quality is 80 mm- mrad. Through exploitation of intermodal dispersion of the fiber, intensity variations in the output from the fiber due to speckle are suppressed to a visibility of < 7%.
