Laser Radiation Detector

Laser radiation is measured in the same radiometric measurement units as polychromatic light sources. But Laser detectors are generally listed separately since they are designed specifically for laser measurement and calibrated accordingly. A typical Laser detector consists of a photodiode with or without attenuating filter calibrated at the Laser wavelength(s). 

Measurement of Laser Power in W 

To measure Laser power the detector area must be larger than the LASER spot size on the detector surface so that the total beam power is measured. Flat surface Laser detectors offer active areas of up to 1cm². Bare photodiodes can measure very low Laser power levels in the picowatt range but are limited to about one milliwatt before saturation of the photodiode. The upper range limit can be extended using neutral density filters. When using bare photodiodes or attenuating filters back reflected Laser radiation must be considered for both hazard and application implications.


Measurement of Laser Power Density in W/m² 

Measuring Laser power density is identical to the measurement of irradiance. Flat surface Laser detectors can be used to measure the Laser power density if the Laser radiation overfills the detectors active area.
For Laser hazard measurements a Laser power density detector with a 7mm diameter active area representing the maximum opening of human eyes pupil is recommended.


Flat Surface Laser Detector

The LP-9901 flat surface Laser detectors feature a 7mm Diameter active area. The neutral density filter extend the measurement range up to 50 mW in the spectral range from 400 nm to 1100 nm.


Traceable Laser Safety Detector Calibrations

Calibration of radiant power in W is performed at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
