Why is Copper So Difficult to Weld with Lasers?
Copper is an industrial powerhouse, but when it comes to laser welding, it turns into a real troublemaker. Copper’s unique material properties make it one of the most challenging metals to weld with traditional infrared lasers, often causing defects like porosity, spatter, and incomplete fusion. Despite its exceptional conductivity, copper’s behavior under laser exposure presents […]
What Is Laser Black Marking and How Does It Work?
Many manufacturers struggle to achieve high-contrast, permanent marks on delicate materials. Laser black marking creates deep black marks without damaging surfaces. It’s clean, durable, and ideal for high-precision applications. Laser black marking has become the go-to method in industries needing fine, high-contrast, and permanent markings. But how exactly does it work? And which materials and […]
A Deep Dive into Risk Management: Vivlaser Hosts FMEA Quality Training
How can we identify and mitigate potential risks before they happen? For Vivlaser, this is not just a management question—it is a core principle of product excellence. At Vivlaser, quality is not a slogan. It is an integrated system that governs every stage of our product lifecycle. We believe that relentless focus on detail and […]
What is VCSEL and How Does It Work?
VCSELs are quietly powering the future of 3D sensing, optical communication, and precision electronics — but many engineers still don’t know what makes them unique. A VCSEL (Vertical-Cavity Surface-Emitting Laser) emits light vertically from its surface, unlike traditional lasers. Its structure enables efficient, compact, and scalable laser systems. VCSELs are not just an alternative laser […]
How LiDAR is Powering the Future of Autonomous Driving?
Autonomous vehicles promise safer roads, less traffic, and more freedom. But to truly "see" the world around them, they need LiDAR. LiDAR gives autonomous vehicles the ability to perceive their surroundings in 3D, making real-time, safe navigation possible. LiDAR is more than a sensor. It’s the backbone of machine perception for autonomous mobility. Let’s explore […]
How Blue Lasers Are Transforming Copper Welding?
Copper’s strength is its weakness — high conductivity and reflectivity make it notoriously difficult to weld with traditional infrared lasers. Blue lasers absorb more than 10x better on copper than IR, enabling cleaner, more efficient welding with less energy, no spatter, and perfect seams. Copper is ideal for electricity but a problem for lasers. Its […]
What’s the Difference Between Fiber Laser Handheld Welding and Diode Laser Handheld Welding?
The welding industry is evolving fast. Choosing the right handheld laser welding solution can save cost, improve quality, and boost productivity. Fiber laser handheld welding offers deeper penetration and lower cost, while diode laser welding delivers smoother, splash-free seams ideal for thin materials. The handheld laser welding market is booming. From metal cabinets to precision […]
Can Diode Laser Welding Carve a Niche in the Handheld Welding Market?
Laser welding is hot. But within this booming field, can diode laser welding find its unique position? Yes. Diode laser welding offers unmatched advantages for thin, aesthetic, and splash-free welds that fiber laser systems often overlook. As fiber laser systems dominate the market with deep penetration and wide adoption, diode laser welding quietly serves specific […]
A Complete Guide to the Six Main Types of Lasers and Their Applications
Modern industry moves at the speed of light—literally. Laser technologies are behind everything from smartphone components to eye surgery. Lasers fall into six main categories, each tailored to specific applications with unique strengths and limitations. Choosing the right laser means aligning not just performance, but also integration, cost, and reliability. Introduction — How Lasers Revolutionized […]
What Type of Laser Can Cut Glass Effectively?
Cutting glass with lasers is a technical challenge that requires deep understanding of material-light interaction. Unlike metals or polymers, glass is highly transparent to many common laser wavelengths (e.g., 1064 nm for fiber lasers or 10.6 μm for CO₂ lasers), meaning it reflects or transmits most of the energy rather than absorbing it. This makes conventional laser […]
