Paper Abstract

Laser beams propagating through complex media commonly experience degradation. This experiment investigates the effects of using laser beams with different wavelengths propagating along the same path as a method of mitigating distortion. We recorded intensity measurements of both a red and green laser after passing through a temperature and flow controlled underwater path and explored the effects of wavelength diversity on laser scintillation. Specifically, temperature variations were induced in a 243cm long water tank, containing 500 liters of deionized water using three heating sources. Experiments were performed with a triple pass through the tank for a total propagation length of 980cm. The final experimentation yielded repeatable and significant reductions in the scintillation of the multiple wavelength beam compared to its individual component beams.
