Zusammenfassung:A laser cutting apparatus operable in a wellbore to form radial slots in a subterranean formation penetrated by the wellbore and a casing lining at least a portion of the wellbore. The laser cutting apparatus includes a housing, a deflector system, and an optical member. The deflector system is disposed for rotation about a first axis within the housing and is rotatable about a second axis at a distance from the first axis. The optical member conducts a laser beam incident upon the deflector system.
