Abstract
There are provided using deuterium oxide as a media for transmitting high power lasers to perform laser operations, such as cutting, boring and drilling, a target material. High power laser beams are transmitted through a deuterium oxide beam path to a target material, including material in a pressure containment vessel.
Claims16
An iris laser cutting assembly comprising:
- a. a support ring;
- b. a high power laser delivery system;
- c. an iris cutter comprising a plurality of iris cutting blades, wherein in an open position the iris cutter defines an iris cavity;
- d. a plurality of laser cutters, each laser cutter positioned to direct a laser beam into the iris cavity;
- e. wherein the high power laser delivery system is in optical communication with the laser cutters;
- and wherein the support ring is connected to the iris cutter;
- and,
- f. wherein the iris cutter blades are capable upon closing from the open position to center a tubular in the iris cavity to be cut by laser beams delivered from the laser cutters;
- whereby the iris cutter blades are capable of closing the iris opening.

An iris laser cutting head assembly comprising:
- a. a support defining an opening, the support comprising a linkage capable of attachment in a pressure containment device;
- whereby upon attachment the opening becomes part of a cavity in the pressure containment device;
- b. a laser delivery system in optical communication with a plurality of laser cutters;
- c. an iris cutter comprising a plurality of iris cutting blades, wherein in an open position the iris cutter defines an iris cavity;
- whereby upon attachment in the pressure containment device the iris cavity becomes a part of the pressure containment device cavity;
- d. a plurality of laser cutters, each laser cutter positioned to direct a laser beam into the iris cavity;
- and,
- e. wherein, upon attachment to the pressure containment device, the iris cutter blades are capable upon closing from the open position to center a tubular in the pressure containment device cavity to be cut by laser beams delivered from the laser cutters;
- whereby the iris cutter blades are capable of closing the pressure containment device cavity.
