摘要： Methods, systems, and devices related to downhole wellbore operations such as drilling and completing wells in an earth formation that include a laser device. The method includes lasing a rock and detecting an optical response of the lased rock. It can be determined from the optical response whether the lased rock is responding as specified (e.g. spalling, melting, etc.) If the lased rock is not responding as specified, one or more laser parameters are adjusted to achieve the specified response. Spalling is determined by the detection of sparks, or other light that erratically changes in intensity over time, by an optical detector. The detection of steady light may indicate other types of rock removal mechanisms, such as melt or dissociation.

摘要： A boring method is provided and can include directing a laser beam at an exposed face of a bulk target in a longitudinal direction. The laser beam can be configured to liquefy and/or gasify the target within the laser beam. The method can also include removing, by the laser beam, a channel of predetermined length and width within the target. The method can further include moving the laser beam in a closed loop of predetermined diameter to define a cut portion of the target laterally bounded by the closed loop. A ligament of the cut portion can remain attached to the target. The method can additionally include separating the ligament from the target. The method can also include removing the cut portion from the target after separating the ligament to form a bore.
