Three-Wavelength Modules

A three-wavelength diode laser module integrates three individual laser diodes—each operating at a distinct wavelength—into a single, compact system. These wavelengths are optically combined using precision components such as dichroic mirrors or fiber combiners, allowing either simultaneous or independent output. This eliminates the need for multiple laser systems and streamlines applications requiring multiple wavelengths.

Three-wavelength modules offer:

• Simplified optical alignment
• Reduced footprint and cabling
• Lower power consumption and cooling demands
• Enhanced portability and system integration

These factors lead to greater reliability, faster deployment, and cost savings in complex multi-wavelength applications.

Common combinations include wavelengths in the visible and near-infrared range—such as 405 nm, 520 nm, 635 nm, or 808 nm, 980 nm, 1064 nm. Custom configurations are available based on your specific application needs. Reach out to discuss tailored wavelength and power options.

Yes. Each wavelength can be configured with its own output power, typically ranging from a few milliwatts up to several watts. Analog and digital modulation options are also available, enabling precise temporal control for research, diagnostics, or manufacturing systems.

Akela offers both fiber-coupled and free-space output configurations. Fiber-coupled options support single-mode, multimode, or polarization-maintaining fibers and are ideal for plug-and-play integration into microscopes, optical benches, or OEM systems.

Consider the following:

• Wavelengths required for your materials or targets
• Beam quality (single-mode vs. multimode)
• Power level (mW to watts per channel)
• Modulation needs (analog, TTL, or digital)
• Cooling and thermal performance
• Mechanical format or fiber-coupled output

Our engineers can help guide you to the ideal configuration.

These modules are used across:

• Biomedical and Life Sciences: Fluorescence microscopy, optogenetics, flow cytometry
• Spectroscopy and Metrology: Multi-wavelength sensing, interferometry
• Industrial Applications: Precision material processing, alignment, and inspection
• Environmental and Remote Sensing: Gas detection, vegetation analysis

Our modules use thermoelectric coolers (TECs) combined with heat sinks to stabilize the temperature of each laser diode. This ensures wavelength stability, consistent output power, and long-term reliability—even in high-duty-cycle applications.

We use precision-aligned dichroic optics or fused fiber combiners to merge the beams. Each beam path is tested for power balance, beam profile, divergence, and pointing stability to ensure optimal performance in critical systems.

A reliable manufacturer should offer:

• Deep photonics expertise
• Custom engineering for wavelength, power, and format
• Strict quality control – spectral accuracy, stability, durability
• Fast, responsive support before and after the sale
• Compliance with safety standards (e.g., FDA, CE, ISO)
• Timely delivery to meet project milestones
• Competitive pricing without compromising quality

Akela Laser checks all these boxes with U.S.-based engineering and global service reach.
