Independent of beam geometry and without the need for auxiliary optics, Labsphere's Laser Power Measurement Spheres are ideal for collecting the total radiant power emitted by highly divergent sources, such as laser diodes as well as a collimated laser beam. Accurate, repeatable measurements may be performed quickly and easily without painstaking positioning and alignment procedures. Integrating sphere measurements of laser power also eliminate polarization effects often associated with filter attenuation techniques.

The liquid-cooled Laser Power Measurement Spheres include three sizes of liquid cooled integrating spheres designed for performing power measurements of high power pulsed and continuous wave lasers. Coated with Infragold® High Reflectance Coating for measurements over the 700 nm - 20 µm wavelength range, the liquid-cooled design can handle a maximum power density of 2 kw/cm2 (CW for 1 second exposure at 10.6 µm) while greatly reducing the self emission that would result from an un-cooled sphere.

Labsphere Laser Power Measurement Spheres are offered for applications in the wavelength regions from UV-VIS-NIR to the NIR-MIR. Each laser power measurement sphere is designed to accommodate standard Labsphere detector assembies.

The spheres include two statically placed detector ports. Users can mount two detectors simultaneously to measure laser sources with difference in output wavelength. The sphere can also be used for laser characterization by mounting a photodetector on one port and a spectrometer on the other.

A laser target fits into a port opposite the input beam and is designed to receive the first strike from the laser and disperse its energy into the sphere. Each assembly for the liquid-cooled Laser Power Measurement Spheres has two 0.25 inch NPT fittings to interface to the cooling system.

Normal tap water or a refrigerated coolant such as ethylene glycol may be used as a coolant. If a recirculator is used, consult the manufacturer as to the choice of coolant. The measurement devise is ideal for output measurements from CO2, Nd:YAG, and other infrared lasers with power density less than 2 kW/cm2. The maximum coolant pressure is 15 psi. and the relief valves lifts at 35 psi. Pressure limitation and the coolant outlet temperature should be considered when selecting a coolant base.
