The invention provides a laser radar and a manufacturing method thereof. Through mixed arrangement of emitter devices and detection devices, the laser radar not only reduces energy density of probe laser in a plane vertical to the light propagation direction and improves AELs.p.train limit of the laser radar, thereby achieving purposes of prolonging the laser radar detection distance and expandingthe laser radar detection range, but also reduces impact on existing laser radar paths as far as possible and prevents increasing the size of the laser radar, thereby achieving a purpose of controlling the manufacturing cost and process difficulty of the laser radar. The technical scheme can give consideration to high integration level and low process difficulty under the premise of ensuring highsafety and large detection distance.
