When your optical system needs precise light delivery in a compact package, a fiber coupled laser diode can simplify integration while maintaining controlled optical output. For medical equipment, optical research, and precision treatment systems, wavelength, power, fiber size, and coupling stability all affect system design. BU-LASER provides a 488nm 30mW fiber coupled laser diode module with a 3um single-mode fiber, designed for applications that require concentrated optical transmission. The module measures 30 × 10 × 10mm and supports customizable dimensions and fiber specifications, giving you more flexibility when integrating the laser into compact equipment.

The compact housing helps you integrate the module into equipment where installation space is limited. Meanwhile, the single-mode fiber supports concentrated optical transmission for applications where controlled light delivery is important.
Why Use a Single-Mode Fiber Coupled Laser Module?
A conventional free-space laser source can require additional optical alignment and beam management components. By contrast, a fiber-coupled design transfers the laser output through the fiber, which can simplify optical routing inside your equipment.
For systems using a 3um single-mode fiber laser module, you can benefit from:
- Compact optical integration
- Defined fiber-based light transmission
- Customizable fiber core specifications
- Stable 488nm wavelength output
- Flexible housing dimensions
- Easier routing of optical energy inside compact equipment
This configuration is particularly relevant when your application requires the laser source to be physically separated from the optical delivery point.
488nm Medical Laser Module Applications
The 488nm 30mW module is designed for applications including ophthalmological treatment, medical surgery, physical therapy, and medical optics research. The actual suitability depends on your equipment architecture, treatment protocol, applicable regulations, and required medical certifications.
For example, in a medical optical system, you can integrate the fiber output into a specialized optical assembly to deliver light to a defined location. In research environments, the module can also serve as a compact 488nm light source for biophotonics and medical optics experiments.
Application Comparison
| Application | Why 488nm Fiber Coupling Matters | Typical Integration Focus |
|---|---|---|
| Ophthalmological equipment | Controlled fiber-based light delivery | Optical alignment and output stability |
| Medical surgery systems | Compact optical routing | Fiber interface and power control |
| Physical therapy equipment | Defined light transmission | Treatment head and optical coupling |
| Medical optics research | Stable wavelength source | Experimental optical setup |
| Biophotonics research | Compact fiber-delivered illumination | Fiber specification and beam delivery |
You should validate the final optical output, exposure conditions, and regulatory requirements according to your specific equipment before deployment.
How to Integrate a 30mW Fiber Coupled Laser Diode
If you are developing a new device, a structured integration process can reduce compatibility issues.
- Define the optical requirement: Confirm that 488nm wavelength and 30mW output meet your system requirements.
- Select the fiber configuration: Check whether the standard 3um core and NA 0.13 match your optical assembly.
- Confirm mechanical dimensions: Use the standard 30 × 10 × 10mm housing or discuss a customized size with BU-LASER.
- Check electrical requirements: Design the driver around the specified 6V working voltage and your complete system conditions.
- Verify optical coupling: Evaluate coupling efficiency, fiber routing, and the receiving optical assembly.
- Complete system validation: Test thermal behavior, optical output, lifetime requirements, and applicable safety standards before final production.
This process allows you to select the 488nm fiber coupled laser diode based on your actual system requirements rather than choosing a laser source only by wavelength.
