1. A laser system for freeing downhole equipment from a wellbore comprising:
a laser tool, with an inner diameter larger than an outer diameter of the downhole equipment, the laser tool comprising means for generating a ring-shaped collimated laser beam; and
a work string with an inner diameter larger than the outer diameter of the downhole equipment,
wherein the laser tool is installed on the work string,
wherein the work string is lowered around the downhole equipment, and
wherein upon lowering the work string to a position in which the laser tool is located proximate to an obstruction of the downhole tool, the laser tool emits the ring-shaped collimated laser beam so as to clear out an annulus space between the downhole equipment and a wellbore wall in order to free the downhole equipment.
