105um 520nm 4W Green Fiber Coupled Laser Module

The 105μm 520nm 4W Green Fiber Coupled Laser Module—a medical-grade high-precision optical light source exclusively optimized for professional medical equipment (clinical therapy, surgical ablation, in-vitro diagnosis, biological detection). Tailored to the strict requirements of medical scenarios (biological tissue compatibility, high-precision energy delivery, medical EMC compliance, 24/7 stable operation), this module leverages 520nm green light’s optimal biological tissue interaction characteristics, 105μm ultra-fine precision fiber coupling, and 4W high-power stable CW output. It features a compact medical-grade structural design, full-dimensional safety protection, and global medical device certification compliance, realizing precise, controllable, and efficient laser energy transmission for medical equipment, and is an ideal core light source for ophthalmic surgery, photodynamic therapy (PDT), biological tissue ablation, and high-end in-vitro diagnostic equipment.

Core Medical-Grade Advantages for Precision Laser Energy Delivery

1. 520nm Green Light: Medical Scenario Optimized Biological Tissue Interaction

• 520nm (±5nm tolerance) pure green direct laser is the optimal wavelength for medical biological applications: it has a controllable shallow-to-medium tissue penetration depth (0.1–3mm) and selective absorption for pathological tissues (e.g., tumor cells, vascular lesions, ophthalmic fundus exudates), minimizing thermal damage to normal surrounding tissues—far superior to red/IR lasers in targeted medical therapy.

• The wavelength matches the absorption peak of common medical photosensitizers (e.g., 5-ALA, HPPH) for photodynamic therapy (PDT), achieving 80%+ photosensitizer activation efficiency and significantly improving the therapeutic effect of tumor/lesion ablation.

• 520nm green light has high contrast in biological tissue imaging (e.g., blood cell, tissue section fluorescence excitation), with no spectral overlap with biological autofluorescence, improving the signal-to-noise ratio of in-vitro diagnostic equipment (flow cytometry, confocal microscopy).

• Narrow spectral linewidth (≤5nm FWHM) eliminates chromatic aberration of the medical equipment’s optical lens system, ensuring consistent laser energy distribution at the fiber output end and avoiding local over-irradiation of biological tissue.

2. 105μm Ultra-Fine Precision Fiber Coupling: Medical-Grade Pinpoint Energy Delivery

• Equipped with medical-grade UV-resistant low-OH multimode silica fiber (105μm core, NA=0.22), the ultra-fine fiber core realizes pinpoint laser energy delivery, perfectly matching the micro-optical path of medical equipment (e.g., ophthalmic surgical probes, minimally invasive ablation catheters, in-vitro diagnostic chip detection ports).

• Upgraded medical-grade space coupling system with dual aspheric glass lenses achieves coupling efficiency ≥80%, minimizing optical loss and ensuring maximum effective power transmission to the treatment/detection site.

3. 4W High-Power Stable CW Output: Meets Diverse Medical Therapy/Detection Demands

• 4W medical-grade stable CW output covers the full power demand of medium-power medical laser applications: low-power (0.5–1W) for in-vitro diagnostic fluorescence excitation, medium-power (1–2W) for laser physiotherapy/tissue activation, high-power (2–4W) for minimally invasive tissue ablation/ophthalmic lesion treatment—one module adapts to multiple medical equipment working modes.
