ND series

Product catalog summary

Product Overview: The document provides technical specifications for Focuslight Technologies Inc.'s ND series high power diode lasers, designed for water cooling. Key benefits include a plug and play fiber connector, high electro-optical efficiency, hermetically sealed housing, and thorough inspection processes for both emitters and fibers.

Specifications: The laser module units are available with nominal output powers of 120W and 150W, with center wavelengths of 980 nm and 808 nm. The wavelength tolerance is ±10 nm, and the spectral width is 20 nm. The wavelength temperature drift is 0.3-0.4 nm/K, with a nominal diode heat sink temperature of 25°C. The operation temperature range for the diode heat sink is +15 to +30°C, requiring a minimum heat sink capacity of 300-340W and a chiller flow capacity of 5 l/min at 4 bar water pressure.

Electrical Data: The maximum operation current ranges from 65A to 90A, with a typical threshold current of 8A and operation voltage of 6V. The typical slope is 2.3-2.4 W/A, and the electro-optical efficiency is 37-40%.

Fiber Connection: The fiber core diameter is either 200 µm or 400 µm, with a numerical aperture of 0.22. The fiber optic connector types include SMA905 and LD80.

Package and Measurement Conditions: The dimensions of the laser modules are 197.8x100x58 mm³, with a basic package weight of 2.2 kg. The storage temperature range is -20 to +60°C.

Additional Features: The pilot beam has a minimum output power of 1 mW at a wavelength of 635 nm, with a voltage of 5V and a maximum current of 40 mA. Temperature sensors include NTC & Pt100, and the fiber coating is non-AR coated. Wavelength stabilization is not available.

Other Information: The document notes that all products are patent pending and subject to change without notice.
