A system, method, and a computer program product for caching multi-dimensional data based on an assumption of locality of reference. Robustness, compactness, thermal and laser stability along with placement of multiple elements in the same space provides femtosecond laser system with high efficiency of stretching and re-compression of femtosecond pulses. Stabilization of the liquid level in the box consequently decreases the interference to imaging results of an imaging device due to the level changing of the couplant liquid and improves the diagnostic accuracy of the imaging device.
