Laser Doppler velocimetry by optical self-mixing in vertical-cavity surface-emitting lasers

In this letter, we analyze experimentally the responsivity of vertical-cavity surface-emitting lasers (VCSELs) to backscattered Doppler radiation. Their responsivity is strongly enhanced by at least 10 dB with the selection of one polarization state in the detection beam and by the presence in VCSEL...
