That's right. LIDAR systems are under development by the US navy, as it has certain advantages over RADAR.
LIDAR isn't useful for wide-ranging scanning, like RADAR is, because of the direct nature of the beams. But if you spot an incomer with RADAR, then lock him up with LIDAR, you can then shut down your active RADAR, thus NOT telling all and sundry your exact location. LIDAR, being absolutely directional, doesn't have scatter lobes; it doesn't tell anyone where you are, but theoretically you can stillue it to vector in your interceptors.
