1. An apparatus for providing tissue therapy, the apparatus comprising:
a direct current (DC) voltage source; and
a field generator having a plurality of electrodes configured to provide an electrical field across the plurality of electrodes; and
a laser light source configured to deliver laser light along a laser light path to a portion of a biological medium during application of the electrical field;
wherein the DC voltage source is electrically connected to the electrodes;
wherein a first one of the electrodes comprises an electrically conductive surface configured to contact the biological medium, and a second one of the electrodes is configured to not conduct current to the biological medium;
wherein the field generator is configured to apply the electrical field to the portion of the biological medium such that free electrons are diverted away from the portion of the biological medium along the laser light path; and
wherein the biological medium comprises skin or tissue.
