1. A surgical device comprising:

  • an optical fiber having a proximal end, a distal end, and a neutral axis at the distal end,wherein the optical fiber is configured to generate a steam bubble from light energy conveyed out the distal end of the fiber, the proximal end is operatively connected to a light source, and the distal end comprises a tip with a tilted edge that is non-orthogonal and non-symmetrical with respect to the neutral axis, the light energy being conveyed out the tilted edge to generate the steam bubble off-angle from the neutral axis of the optical fiber,wherein the titled edge forms an angle such that at least a portion of the light energy (i) is incident on the tilted edge at an angle of incidence that is less than a critical angle and (ii) exits the optical fiber from the tilted edge.
