Introduction
============

All but one of the detected extragalactic very high energy (VHE) gamma ($\gamma$) ray sources so far are active galactic nuclei (AGN) of the BL Lac type. These objects are characterized by a highly variable electromagnetic emission ranging from radio to $\gamma$-rays, and by continuum spectra dominated by non-thermal emission that consist of two distinct broad components. While the low energy bump is thought to arise dominantly from synchrotron emission of electrons, the origin of the high-energy bump is still debated. Leptonic models ascribe it to inverse Compton processes that either up-scatter synchrotron photons (synchrotron-self Compton \[SSC\] models, Marscher & Gear 1985, Maraschi et al. 1992), or to
