1. A laser system comprising:
a source laser coupled to first mirror device opposing a second mirror device and configured to generate a resonating laser beam between the first mirror and the second mirror; and
a piezoelectric device configured to attach to the second mirror device and characterized by a refractive index such that one or more voids is changed by applying an energy to the piezo electric device to cause a change in a value of the refractive index by more than 0.0001 to allow the resonating laser beam to traverse through a portion of the second mirror device.
