High-power fiber lasers do amazing work, but they also carry energy that does not always stay in the core. Some of this extra energy travels in the cladding. If it builds up, it can heat your components, damage coatings, or hurt system stability.
This is why safe cladding power management matters. It keeps your laser clean, steady, and ready for long runs.
In this blog, we will share:
• What cladding power is
• Why it becomes a problem in high-power systems
• How a Cladding Power Stripper helps you control it
What Cladding Power Really Is
Cladding power is light that leaks into the outer layer of the fiber instead of staying in the core. This can happen when pumps launch light into the fiber or when small reflections shift energy out of the core.
You cannot ignore this stray energy. It can heat the fiber and lead to long-term damage. So you need a clear plan to remove it before it causes trouble.
Why High-Power Systems Feel the Most Risk
High-power fiber lasers carry strong pump light and signal light. When they reach higher power levels, even small leaks create heat. This heat can build up fast in tight spots such as fusion splices, connectors, and coatings.
If you let cladding energy stay inside the fiber, it can leave burn marks or weaken the fiber strength. Many system failures come from unmanaged cladding power.
You avoid this risk by stripping the cladding energy before it spreads.
How a Cladding Power Stripper Works
A Cladding Power Stripper pulls unwanted light out of the cladding while it keeps the core signal safe. It uses a special structure that absorbs the cladding light on purpose. It removes this extra energy as heat in a controlled way.
You get a fiber that stays cooler and more stable. Your laser can run longer without stress or drift.
How This Helps Your Laser Stay Stable
When you clean up cladding energy, you protect your signal. The core stays uniform, and the heat stays low. Your system runs with fewer hot spots, which means better long-term reliability.
This also helps with beam quality. When the core stays stable, the output stays clean and smooth. Many OEMs count on this level of control when they design their modules.
Where You Should Place the Stripper
You usually place a Cladding Power Stripper right after the pump combiner or any point where pump energy enters the system. You also use one near the output stage if you expect strong reflections.
Good placement makes the entire system safer. It also makes the heat flow easier to manage inside tight mechanical layouts.
Why Every High-Power System Needs This Step
Cladding energy becomes a threat only when it builds up. If you clear it early, your system stays steady. If you skip this step, the heat can harm coatings or distort the fiber.
A Cladding Power Stripper gives you a simple and dependable way to protect your design. It removes heat at the source and lets your fiber laser work without stress.
Final Thoughts
Safe cladding power management is not only helpful. It is necessary for high-power fiber lasers. When you use a well-designed Cladding Power Stripper, you protect your core signal, control heat, and build a system that handles long hours with confidence.
A small step like this gives you strong system health and fewer surprises in the field.
