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 3 is a bit of a departure from my planned sequence for this series. A colleague has graciously permitted me to share a slow motion video that he produced of a generic side fire fiber delivering a single pulse of holmium energy into a beaker of water. Herein I hope to demonstrate that surgical fiber performance can be modeled/predicted, and quite accurately, and that there isn't anything mysterious or magical involved. Sure, some aspects of laser surgery are extremely complex, like laser-tissue interactions, but the tools that science provides do allow us to design devices intelligently. That's my company's motto, after all:...

Part 1 of this series was mostly a review of Snell's law and Fresnel reflections as they explain the weird output of bevel polished fibers. Here we see some more Snell and Fresnel issues and the earliest Band-Aid® treatments designed to mitigate these issues. Part 2: Abe's Solution(s) Before we get into what Abe saw as solutions to the issues outlined, we should probably address the problem that I alluded to in Part 1: the disappointing results of polishing a fiber at the calculated TIR angle for lateral redirection of the output. In so doing, you’ll more fully understand why...

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.
