The 525nm Fiber Coupled Laser series covers 3.2–70 W of fiber-delivered green output for machine vision illumination, optical inspection and fluorescence or spectroscopy excitation. Twelve power steps are available, and the practical selection driver is fiber core size versus the illumination field you need to fill.
Power & fiber — 3.2–70 W across twelve models; 50, 60, 105 or 200 µm core, fiber NA 0.22, FC or SMA905 output, 0.6–1.5 m lead
Spectrum — 520–530 nm centre (525 nm typical), 8–10 nm FWHM; a 532 nm option is available at 35 W
Beam — NA 0.2–0.22 at 95% power, 85–90% field homogeneity with collimating lens
Drive — 2 A typical; DC 16–21 V single-channel up to 5 W, then series-connectable channels (66–82 V at 15–20 W, up to 264–328 V across eight channels at 70 W), 12–12.5% electro-optical efficiency
Cooling — conduction cooled; 23–25 °C coolant temperature required
Tell us the application, target power and fiber interface, and we will confirm the matching model and release its full specification.
This 525 nm fiber-coupled semiconductor laser family provides compact, stable green-laser output across multiple power and fiber-core configurations. The modules combine high power density, efficient conductive cooling, and flexible fiber delivery for integration into precision optical systems.
Each product image and dimension drawing is paired with the exact model specification shown in the same table. Select the required power, fiber core, and output termination before confirming the mechanical interface.

Notes
Photoelectric data are referenced to the test conditions stated in each source specification; most source sheets use 25°C.
Output power, fiber specifications, connector type, and fiber length can be customized where indicated.
Use appropriate electrostatic-discharge protection during transport, storage, and operation.
Clean the fiber end face before use and avoid contamination or damage.
Operate the laser with a constant-current supply and within the rated current, voltage, and power limits.
Provide effective cooling; the source sheets generally recommend a cooling-water temperature of 23-25°C.
Avoid direct eye or skin exposure to laser radiation and follow wavelength-appropriate laser-safety procedures.
Do not bend the fiber sharply; follow the minimum bend-radius guidance in the applicable source specification.
Definition — What Is a 525 nm Green Laser?
A 525 nm green laser is a semiconductor laser source that emits in the green part of the visible spectrum, produced directly by an InGaN laser diode rather than by frequency-doubling an infrared laser. Because 525 nm sits close to the peak of human photopic sensitivity, a green beam looks far brighter to the eye and to most silicon detectors than an infrared or red beam of the same optical power — which is why green is the working wavelength for visible alignment, projection, structured-light imaging, and fluorescence excitation.
Green also behaves differently on the material side. Copper, gold, and other highly reflective metals absorb visible green energy several times more efficiently than they absorb 1064 nm, and water attenuates blue-green light far less than infrared. Those two physical facts drive most of the industrial demand for 525 nm sources.
LUMEXIS supplies 525 nm green lasers in fiber-coupled and free-space configurations, with CW and modulated operation, for machine vision illumination, laser display and projection engines, life-science and analytical instrumentation, underwater imaging, alignment and metrology, and research systems.
Why Choose LUMEXIS Green Laser Module
We design and build the laser ourselves. LUMEXIS is an engineering-led laser manufacturer with R&D in Wuxi and a manufacturing base in Taizhou. Optical and optomechanical design, semiconductor laser packaging, fiber coupling, drive electronics and firmware, thermal design, and test-method development are all in-house. When you ask why a spec behaves the way it does, you talk to the people who designed it.
Vertically integrated production. Every module runs through the same controlled flow: incoming inspection → chip test → die bonding and chip-on-submount assembly → mounting and soldering → fiber coupling and alignment → hermetic sealing → burn-in screening → final performance test. Assembly is done in a cleanroom with controlled temperature, particulate, and handling.
Reliability screened in, not inspected in. Our line includes COS aging systems for early-life failure screening, bare-bar test systems, high/low temperature cycling chambers covering the full operating window, vacuum reflow sintering for void-free solder joints, parallel seam welding for hermetic packages, automatic gold wire bonding, and automated fiber coupling stations. Units that drift during aging never reach a customer.
Customization that stays practical. Wavelength bin, output power, fiber core and NA, connector, package format, modulation interface, and cooling approach can be specified to your system. We would rather adjust the source than ask you to redesign around it.
Documentation your engineers can use. Test data with stated conditions, honest tolerances, and specifications written to be designed against — not to win a spec-sheet comparison.
LUMEXIS holds 170+ patents and software copyrights (including 38 invention patents), participates in drafting national and industry laser standards, and ships to customers in more than 30 countries.
Tell us your application and we will recommend the configuration — or build one.Request a quote →
