R. Falciai et al., ND-YAG LASER DELIVERY SYSTEM UTILIZING GRIN ROD LENSES AS FOCUSING COLLIMATING OPTICS, Optics and Laser Technology, 26(6), 1994, pp. 409-412
A sequential electromechanical system capable of delivering the radiat
ion coming from a medium power Nd:YAG laser to an array of multimode o
ptical fibres is presented. The system utilizes GRIN-rad microlenses a
s focusing-collimating optics. A focusing unit positioned at the fibre
distal-end, which can work in two different configurations, has also
been designed and constructed.
