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...

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.

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 angle (near maximum NA). We’ll be using computer-generated ray traces to depict what happens with a typical laser focus condition (aka laser launch condition) when coupling to a series of...

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 and useful. Lenses are required to focus laser light. You may ask yourself, “So what? It’s a minor exploitation of poetic license.” I agree, but I needed an entrée suitable for...
