Abstract
We present a novel strobe photography system capable of recording a full dynamic sequence in a single camera acquisition, with an effective frame rate of 1 million FPS. This system has been utilized to study pulsed laser ablation from a 1064 nm, 6 ns laser pulse incident on biological tissue. Image sequences enable the extraction of physical parameters, include shock wave and ejecta velocities, and accelerations. Encoding contrast with shadow photography enables the estimation of the mass ejected for a single ablation pulse.
