摘要：
Photon drag detectors are usually used with high power pulsed lasers. Their application with CW lasers is rather limited due to the very low responsivity of the detectors. In this investigation, we have measured experimentally the output powers of CW FIR lasers of the order of a few milliwatts using Ge, Si and GaP photon drag detectors.
