1. Product Overview
Model 03BCK is a multi-functional fiber-coupled diode laser module under RealLight self-developed AW series. Adopting standard TO-CAN hermetic packaging and precision fiber coupling technology, it is available in single-mode and multi-mode configurations, covering mainstream visible wavelengths of 405 / 450 / 520 / 638 / 650 nm. Compact size with uniform and stable beam, it supports customized fiber specifications, output power and optical functions. Widely applied in biomedical instruments, alignment aiming, chemical spectroscopic analysis and miniature precision laser processing, it serves as a low-cost standardized light source for lightweight optical equipment and portable detectors.

2. Core Product Advantages
2.1 Miniature Standard TO Package for Easy Integration
Adopted universal sealed TO-CAN shell with ultra-small footprint, occupying minimal internal space of equipment. It can be easily embedded into handheld detectors, desktop analyzers and compact medical devices, simplifying mechanical design and supporting mass OEM matching.

2.2 Dual Single/Multi-Mode Options for Customized Beam Demand
Single-mode versions support 4/6/9 μm core fiber with low divergence and pure mode, ideal for high-precision spectral excitation and microscopic optical testing. Multi-mode variant uses 105 μm large-core fiber with higher output power and uniform spot, suitable for large-area irradiation, aiming beams and low-power processing. Custom single-mode fiber output is available for all variants.

2.3 Narrow Spectrum & Controlled Wavelength Drift for Long-Term Stability
Full series spectral linewidth FWHM ＜ 3 nm, wavelength tolerance ±10 nm, temperature-induced wavelength shift only 0.3 nm/℃. Minimal wavelength fluctuation under varying temperatures ensures repeatable data for fluorescence and quantitative analysis. Optimized electro-optic design guarantees low power decay during continuous long-hour operation.

2.4 Rich Customization for Special Working Conditions
Customizable items include various output power grades, extended fiber length, anti-reflection coating on fiber end faces and dedicated 650 nm red aiming module. Standard FC/PC and SMA905 fiber connectors match most optical lenses, spectrometers and beam transmission components directly.

2.5 Standardized Electrical Parameters for Convenient Driver Matching
Each wavelength is equipped with well-matched threshold current, operating current and voltage with balanced differential efficiency. No complicated driver circuit modification is required, shortening equipment R&D cycle and hardware cost.
