FG series

Product catalog summary

Product Overview: The FG series high power diode lasers by Focuslight Technologies are designed for thermoelectric cooling, offering high electro-optical efficiency and hermetically sealed housing. Each emitter and fiber undergoes 100% incoming inspection, and lasers are subject to 100% outgoing inspection.

Specifications:

Laser Module Unit: Available in two models with nominal output powers of 35W and 60W, center wavelengths of 808nm and 981nm, and wavelength tolerances of ±3nm. The spectral width is 4nm (FWHM), with a wavelength temperature drift of 0.3nm/K and 0.4nm/K respectively.
Operation Conditions: The nominal diode heat sink temperature is 20°C, with an operational range of +15°C to +30°C. Minimum heat sink capacities are 80W and 110W.
Electrical Data: Maximum operation currents start at 53A and 80A, ending at 64A and 96A. Typical threshold current is 8A, with operation voltages of 2V and slopes of 0.8W/A and 0.9W/A. Typical E/O efficiencies are 39% and 45%.
Fiber Connection: Fiber core diameters are 100µm and 200µm, with a numerical aperture of 0.22. The fiber optic connector is SMA905, with a fiber length of 1.5m for the 35W model.
Package: Dimensions are 136.3x56x34 mm³, with a basic package weight of 0.85kg. Storage temperature ranges from -20°C to +60°C.

Additional Features: Includes temperature sensors (NTC & Pt100) and a protection filter with high reflection bandwidth of 1030-1130nm (>99% S&P polarized). Measurement fiber is non-AR coated.

Notes: The document specifies that all products are patent pending and subject to change without notice.
