Calibration of optical fiber Laser source

The Standards and Calibration Laboratory (SCL) has set up facilities to provide calibration for optical fiber laser sources. The measurements of wavelength, output power level and output power stability of an optical fiber laser source fitted with FC/APC connectors are detailed. The wavelength is directly measured by the laboratory wavelength meter. The measurement uncertainty obtainable by this calibration method is better than 1 picometer (pm). The output power level is the summation of the measured power by the laboratory Electrically Calibrated Pyroelectric Radiometer (ECPR) and the insertion loss between the source and the ECPR with measurement uncertainty better than 0.5 dB. The output power stability is measured in accordance with the international standard ISO 11554. The output power stability is evaluated by measuring fluctuation of the measured emission intensity. The laboratory ECPR has 0.001mW power reading resolution which is sufficient to quantify stability as small as 0.015 dB.
