The 792nm Fiber Coupled Laser series covers 75–150 W for Tm-doped fiber laser and amplifier pumping. Every model carries 1850–2100 nm return-light isolation, which is what protects the diode when the 2 µm signal finds its way back down the delivery fiber.
Power & fiber — 75–150 W across three models; 105, 200 or 400 µm core, fiber NA 0.22, SMA905 or pigtail output, 1.5 m lead
Spectrum — 787–797 nm centre (792 nm typical), 5 nm FWHM, 0.3–0.4 nm/°C temperature drift
Protection — 1850–2100 nm return-light isolation for 2 µm signal rejection
Drive — 6–12 A at 16–35 V depending on configuration, 42–45% electro-optical efficiency
Cooling — conduction cooled; 23–25 °C coolant temperature required

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.
