As photons traverse the epidermis and adipose tissue, isotropic scattering rapidly diffuses the collimated beam, converting it into a divergent volume of radiant energy. At a depth of $2\\text{ cm}$, the initial irradiance ($I_0$) can drop by more than $80\\%$. To compensate for this profound loss without burning the patient, the peak power must be elevated while adjusting the temporal profile of the wave.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure
