From Abe to MoXy™ and Beyond; Part 2 -- Abe's Side Fire Solution(s) January 09 2017

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...

How to Cleave Surgical Fibers November 22 2016

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...

What are Holmium Laser Fiber Sizes, Really? November 21 2016

Section 502 of the Federal Food, Drug and Cosmetic Act (FFDCA) says that a device is misbranded if its labeling is false or misleading in any particular. Maybe the FDA doesn’t read Urology? I’m referring to a paper that appeared in the journal Urology a couple of years ago*, questioning the veracity of holmium laser fiber manufacturers in describing the diameters of their fiber devices. The conclusion was that nobody told the truth. That...

The Power of Collimation IV: Going the Extra Mile November 08 2016

This final Chapter in the blog series, "The Power of Collimation", explores the apparent paradox that ProFlex is able to reject potentially damaging, high angle laser energy within the focus while continuing to deliver more laser energy to the stone than any other holmium laser fiber. 

 

The Power of Collimation III: Moses’ Enthalpy November 07 2016

At InnovaQuartz, we developed a method of making very precise, tiny lenses directly upon the face of an optical fiber. In this third Chapter of The Power of Collimation, I’ll describe just how important this subtle feature really is to the performance of holmium laser URS. In the first Chapter of this blog series, I discussed why holmium lasers launch light into fibers at a substantial fraction of their maximum propagation...

The Power of Collimation II: Bullets, Balls & Skipping Stones November 07 2016

110% power transmission from a 273 micrometer core holmium laser fiber is not fantasy. We see it every day. Learn how.

 

The Power of Collimation I: “I’m going to focus like a laser beam…” November 07 2016

Bill Clinton and George W Bush both promised to 'focus like a laser' on the economy. I'll leave the politics to others and focus like a lens on the lack of scientific rigor for this turn of phrase. At risk of appearing pedantic, I have to point out that lasers aren’t actually focused at all. In fact, collimation (parallelism) is one of the characteristics of laser light that make it unique...

Smooth Passage™ Holmium Fiber Tips on ProFlex™ LLF August 29 2016

In the course of studying other manufacturers' holmium laser fibers we sometimes observe surprising differences. In this case, we knew that our tips were different -- heck, we gave them a special name -- but  just how much difference they made was the surprise.      The two fibers in the photo are "1000 micron", meaning they have either a 910 μm or 940 μm core inside a 1 mm diameter glass cladding. The upper...

IQ honored as Best Precision Fused Silica Component Manufacturer (2016) August 19 2016

  InnovaQuartz pioneered the use of carbon dioxide lasers for manipulating and machining fused quartz and fused silica glasses under computer control and microscopic imaging way back in 1991 when our founder, Stephen Griffin, gambled that his ideas would actually work and built the first laser system in his 80 square foot laundry room. Our first sale was 6 months after the first dollar was spent and we sold more...
