DK Photonics

In high-power laser systems, there’s almost no room for trial and error. When you’re working around kilowatts of optical energy, even a tiny amount of back-reflection can cause performance dips… or worse, physical damage. That’s exactly why the 1064nm High Power Circulator from DK Photonics has become such a dependable component in modern laser setups. I remember the first time I worked with a fiber laser team struggling with unstable signal routing. Every time they pushed the power even slightly higher, reflections from one of the optical paths messed up the entire alignment. A technician said, “I wish there was something that handled isolation AND kept the directionality clean.” Well, that’s pretty much what this circulator does. Why the 1064nm Range Matters So Much The 1064nm wavelength is the heart of many industrial fiber lasers—cutting, welding, engraving, telecommunications, scientific setups… you name it. You’ll find Yb-doped fiber lasers everywhere, and they almo...

In today’s digital world, data demand has grown so fast that even strong networks struggle to keep up. I remember speaking with a small ISP owner last year who said, “Every time we add new users, our fiber feels like it shrinks.” He wasn’t wrong. Traffic has multiplied at a rate that sometimes feels unrealistic. According to several industry reports, global data usage increases by roughly 25–30% every year, which naturally pushes network teams to find better ways to use the existing fiber they already have. That’s exactly where a DWDM Mux/Demux comes in. If you’ve ever wondered how a single piece of equipment can multiply fiber capacity without the need to dig, rebuild, or expand infrastructure, DWDM technology is one of the most practical answers. Why DWDM Mux/Demux Has Become an Industry Backbone DWDM (Dense Wavelength Division Multiplexing) works by sending multiple wavelengths through a single fiber. Instead of pushing one signal at a time, you get dozens—sometimes up to 96 ...
