From: Influence of laser beam intensity profile on deep bone ablation in laser osteotomy

Ablation profile obtained using laser with a tophat and b Gaussian intensity distribution. The measured beam profiles of both lasers are also shown on the ablation profile with red curves. The scale of the CT scan and beam profile measurements are adjusted to be the same. Variation of beam size, crater size, and energy efficiency are shown in c tophat and d Gaussian intensity distribution.
