Abstract: The present embodiments providing methods, systems and apparatuses of protecting a surface during laser machining. In some embodiments, a method of protecting a surface during laser machining comprises: directing a fluid into a cavity of an object being laser machined, where the fluid does not have laser absorption properties; and directing a plurality of laser pulses at a wall of the object being laser machined, where the laser pulses are configured to form a hole through the wall such that at least one laser pulse passes through the hole and enters the cavity while the fluid is directed into the cavity such that the laser pulse is incident on the fluid and a surface together in order to inhibit backwall damage.
