Abstract
A laser cutting apparatus conveyable within a casing lining at least a portion of a wellbore that extends into a subterranean formation. The laser cutting apparatus includes a housing, a deflector, a motor, a sensor, and a processing device. The deflector rotates relative to the housing to direct a laser beam to form a radial slot extending through the casing and into the subterranean formation. The motor rotates the deflector. The sensor generates information related to depth of the radial slot in real-time as the radial slot is formed by the laser beam. The processing device receives the information generated by the sensor and causes the motor to rotate the deflector based on the received information.
