Apparatus and system to drill a bore using a laser

A system comprising:

• a first umbilical having an elongate fluid conduit having a leading end and a surface end;
• a fluid source coupled to a surface end of the fluid conduit of the first umbilical;
• a deflection member connected to a leading end of the first umbilical and having a drive gear, a proximal end, a distal end, a laterally directed exit port intermediate the proximal and distal ends, and at least one deployable seal having at least a portion disposed intermediate the proximal end and the laterally directed exit port;
• a second umbilical having a plurality of elongate optically transmitting fibers and an exterior portion having sized and shaped to be engaged and moved by the drive gear of the deflection member in a direction generally coincident with a portion of an axis of the second umbilical adjacent to the drive gear;
• a laser light power generator optically coupled to a surface end of the plurality of optically transmitting fibers;
• and
• a drill head connected to a leading end of the second umbilical and having an optical element to condition laser light received through the optically transmitting fibers of the second umbilical;
• wherein the deflection member is positionable within a primary bore using the first umbilical;
• and
• wherein the second umbilical is receivable through an umbilical pathway adjacent the drive gear and through the lateral exit port of the deflection member, and movable through the pathway by operation of the drive gear to engage and advance the exterior portion of the second umbilical to advance the drill head to extend a lateral bore formed laterally adjacent to the lateral exit port.
