John Brekke’s fiber design from 1994 is one of the few lateral fiber designs of the era that remains on the market today, marketed as Scatterfree™ by Laser Peripherals. As can be seen in figures 10 and 11 (below the next paragraph) taken from the first patent, the concept is simple and it does basically work. In contrast to Pon, however, Brekke failed to properly identify the true sources of the unwanted emissions from unfused fibers. Quoting the patent, in reference to figures 5 and 6 immediately below, “The reflected light 27 and light 29 are unwanted and potentially unsafe...

The 1990s saw a boom in laser TURP (Transurethral Resection of the Prostate) using mostly Nd:YAG lasers. Nd:YAGs showed promise for lowering the classical side effects of standard TURP, where a hot wire loop is used to melt/carve away strips of hyperplastic tissue; their CW (continuous wave) output produced smoother surfaces than holmium lasers do, they did not strongly interact with the sterile irrigation fluid and were less damaging to fibers than holmium lasers. Laserscope’s ADD-Stat™ fiber -- the progenitor to the Model 2090 used in the GreenLight™ revolution of 2000 -- was a fairly popular device that was used...

Part 1: Fiber Optics Fundamentals (a prerequisite to understanding side fire fibers) I’ve been told a half dozen tales that purport to describe the origin of fiber optics and likely as many claiming to describe the first side fire fiber, but there is little or no evidence for any stories I have heard over my 30+ years in the field…except the tale of “the Hitachi patent”. Anyone working in side fire fiber design has likely heard of this infamous patent, but I'd venture few have read it. The Hitachi fiber is the earliest patented side fire fiber that I have...

InnovaQuartz is pleased to offer a low cost but high performance solution for inspecting SMA (and Trimedyne in January 2017) terminated laser surgical fibers. This battery powered (batteries included) microscope is equipped with a thread-free SMA (or Trimedyne) port that positions the fiber input face within the field of view with acute angle illumination from below. Every detail of the connector face is exposed: scratches, dirt and burns are detected and may be corrected before risking the laser optics. Simply slip the connector ferrule into the aluminum adapter and flip on the light.

How to Cleave Laser Surgical Fibers Purpose: Provide simple instructions for reprocessing flat tip bare fibers for laser surgery. Summary: Clean cut and flat optical faces are necessary for surgical efficacy in laser surgery. Badly cut fibers deliver energy to target tissue less efficiently and degrade more quickly than properly cut fibers. Step-by-step instructions…. Rationale: A.A. Griffith developed the first theoretical model for fractures during WWI, inaugurating the Science of Fracture Mechanics. As luck would have it, Griffith studied glass fibers. Telecommunications fibers are made of fused silica -- just like laser surgical fibers -- and more telecom fibers are...
