B749 is a photon drag detector that utilizes the photon drag effect in which carriers created by input photons are dragged in the direction of
photons, generating an electromotive force. B749 ensures high-speed operation even at room temperatures and has high sensitivity in the 10 m
band, making it well suited to detection of CO
2
lasers. An easy-to-use detector module integrated with a preamplifier (B7506-01) is also available.

The Ge element mounted in the detector package is susceptible to shocks and drop impacts. Handle the detector with
extreme care.
Do not allow light higher than 10 MW/cm
2
to strike the detector element, because the element surface might be damaged.
