JOURNAL FREE ACCESSThe gold vapor laser emitting a multimode beam has been studied to compare to the continuous wave argon-pumped dye laser in terms of photodynamic effects at several institutes, however the focusing of the beam (44mm in diameter) into optical fibers for delivery with a less coupling loss is a technical problem. We studied three types of coupling lens to make the most efficient coupling system for a 600μm quartz fiber. Using a lens being flat on one side and convex on the other with 85mm of focal distance among the three lenses, 1.15W of average output from the 600μm quartz fiber was obtained for 4.5W of average laser output. We discussed about important factors to increase the coupling efficiency on the basis of the optical theory of laser beam focusing technique for optical fibers.View full abstractDownload PDF (329K) -
