Laser delivery systems consisting of flexible optic fibers used to deliver laser energy of visible and near-infrared wavelengths. These systems include a flexible fiberoptic cable with a silica core, an outer cladding and protective sheath, and a handpiece; they are typically available in core sizes of 400, 600, and 1,000 micrometers. Tips are designed according to the procedure to be performed (e.g., sculpted quartz for contact procedures, bare or side-firing for noncontact procedures); some systems permit the coupling of disposable laser fibers to the laser unit. Low-hydroxyl material of high numerical aperture is required by some systems for effective energy transmission.
