A catheter system for treating a vascular lesion within or adjacent to a vessel wall includes an energy source, a plurality of energy guides and a system controller. The energy source generates energy. The plurality of energy guides receive energy from the energy source. The system controller controls the energy source so that the energy is sequentially directed to each of the plurality of energy guides in an advancing wavefront. The system controller controls a firing rate of the energy source to each of the plurality of energy guides. The system controller can control a firing sequence to the plurality of energy guides so that the advancing wavefront is generated toward the vascular lesion from near the balloon proximal end and from near the balloon distal end. The system controller can control the energy source so that light energy from the energy source is alternatively directed to at least two of the plurality of energy guides at a different firing energy level from one another. The energy level can be based on pulse width, wavelength and/or amplitude of the energy pulse(s).
