From optical lithography for semiconductor manufacturing to the micromachining of small structures, lasers are finding their way into an increasingly diverse number of applications. In support of these applications, the Optoelectronics Division provides calibration services at laser power levels from nanowatts to kilowatts and pulse energy levels from femtojoules to megajourles. Wavelength ranges include the standard ultraviolet, visible, and near-infrared laser lines. In addition to standard laser lines, the Division has a tunable laser ensemble that can provide measurements at additional laser wavelengths upon request. Detailed information about the Division's calibration service capabilities can be accessed by selecting the appropriate button on the left.

Since 1967, the Optoelectronics Division and its predecessors have been providing calibrations of detectors and power meters used to determine the output power or energy of lasers. These calibrations are based upon a family of standards in which the temperature rise resulting from absorbed optical power or energy is compared to that caused by dissipated electrical power or energy. Thus they are traceable to SI units through electrical standards of voltage and resistance. Each standard - the Optoelectronics Division currently uses seven - is designed for a particular range of power or energy level for cw or pulsed radiation, and a particular range of wavelengths, as shown below. This assembly of standards and measurement systems represents the best overall capability of its kind in the world.
