The 790nm Fiber Coupled Laser is a single 30 W configuration for Tm-doped fiber laser and amplifier pumping. It is the entry point of the 79x nm pump family, below the 792 nm and 793 nm options, where a modest pump budget and a simple single-channel supply are the priority.
Output — 30 W at 787–793 nm centre (790 nm typical), 5 nm spectral width
Fiber — 200 µm core / 220 µm cladding, SMA905 output, 2 ± 0.1 m lead (customisable)
Beam — NA 0.14–0.15 at 95% power
Drive — 10 A at 8 V from a single channel
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 790 nm fiber-coupled semiconductor laser family combines compact packaging, high power density, stable optical output, and efficient heat transfer. Multiple power and fiber configurations support integration into pumping, sensing, interference, and research systems.

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.
