RGB Fiber Coupled White Laser Module：
"RGB Fiber Coupled" refers to a laser module or light source that combines Red, Green, and Blue (RGB) laser beams and transmits them through a single optical fiber, usually a multi-mode fiber. Here's a breakdown of the term:
What It Means:
RGB: Red, Green, and Blue laser diodes (typically around 638nm, 520nm, and 450nm wavelengths).
Fiber Coupled: The laser beams are aligned and coupled into an optical fiber, so the output light is delivered from the fiber tip instead of free space.
Product Overview - RGB Fiber-Coupled White Laser System
The Triplex Laser System is an all-in-one, turnkey solution that integrates a fiber-coupled RGB laser module, laser diode (LD) drivers, and a temperature control system, offering convenient and stable white light laser output. Designed for ease of use, the system operates simply with a standard 90V–240V AC input, requiring no complex setup.
At its core, the system combines three high-performance laser diodes:
Red (635nm)
Green (520nm)
Blue (445nm)
These lasers are independently driven and controlled, allowing users to finely adjust the power ratio of each channel. The RGB beams are precisely coupled into a single optical fiber, producing a high-brightness white laser output. By adjusting the RGB ratio, a full spectrum of colors can also be generated, making this system highly versatile for applications requiring tunable visible wavelengths.
We offer support for multiple fiber types, including:
Single Mode Fiber (SMF) – e.g., 4μm or 9μm core
Multimode Fiber (MMF) – e.g., 105μm core
Polarization Maintaining Fiber (PMF) – for polarization-sensitive applications
Each laser system undergoes rigorous testing and extended aging procedures to ensure long-term reliability, excellent thermal stability, and consistent optical performance under continuous operation.
