Product Overview:

808nm, 2.5 Watt Laser Diode, Fiber Coupled Package

The RealLight 808nm 2.5 W laser diodes are known for their high efficiency and robust thermal design structure. They are designed to yield lifetimes of thousands of hours at their full rated power for applications including material processing, materials sample illumination and medical uses. They are also used for solid-state laser pumping, beacons, and illumination.

The 9-pin fiber coupled package laser is designed to easily attach to a heat sink for thermal control. The package includes an internal TEC and thermistor for precision temperature control to provide unmatched stability and reliability. The laser also includes a monitor photo-detector for APC (constant laser power feedback) mode of operation

Power-Efficient Laser for Spectroscopic Applications

These 2.5 W lasers offer an efficient electrical input to optical output power. The typical knee for the threshold point is at 500 mA and they achieve full power operation at roughly 4.5 amps of current. The standard fiber has a core diameter of 62.5 μm, 2 mm jacket, and is terminated with a standard SMA-905 style connector. Other connector styles and core diameters are available on request.

This laser is a well-designed and affordable source for laboratory research and for integration into a laser system product.
