A chirped pulse amplifier system having a mode-locked laser and a high-speed pulse selector, wherein the pulse selector modulates output pulses based upon an applied modulation voltage. The second pupil function is preferably different from the first pupil function. In the bonus game, a player selects, one at a time, from an array of windows each associated with a bonus game outcome. The compression wave is reflected on a reflecting surface of the transducer structure to form the tension wave. The method further includes segmenting the lesion using the candidate voxels.
