Acoustic measurement methods can often be used as an inexpensive and robust data collection tool. One such case is using acoustic data to better understand some various nonlinear behaviors of high intensity femtosecond laser pulses. Using acoustic measurements of plasma formation from surface ablation, various nonlinear optical effects can be studied, including plasma filament formation and the Kerr focusing effect. Theory, experimental setup and data collected will be discussed.
