This is how a pulse train looks with EFC.  EFC measures the energy of each and every laser pulse with two independent internal energy meters and adjusts the VSP parameters to keep the laser pulse energies constant. VSP enables the construction of Square pulses.  The control of energy bursts results in the ability to vary the height and the length of a burst resulting in VSP.

This is a Square pulse as compared to a standard laser pulse.  Significant is that the average power and the peak power of a square pulse is nearly the same.  This results in superior treatment outcomes, with less pain and fewer side effects.

When combined together, these superior technologies, along with superior Fotona optics, result in Flat Top energy delivery.  No hot spots like in the Gaussian beam to the right.  Fotona’s EFC, VSP and TOP HAT result in the energy you need, in the place you want and without compromise.  No hot spots, less pain and fewer side effects.
