Abstract

The invention discloses an integrated medium-wave infrared laser radar transmitting device which comprises an LD pump laser source, a laser crystal, a nonlinear frequency doubling crystal and a filter plate which are sequentially arranged. The LD pump laser light source is used as a light source to emit laser to the laser crystal; the laser crystal is used for generating pulse laser and emitting the pulse laser to the nonlinear frequency doubling crystal; the nonlinear frequency doubling crystal is used for doubling the frequency of the laser; the filter plate is used for filtering out part of light beams from the frequency-doubled laser; the LD pump laser source, the laser crystal, the nonlinear frequency doubling crystal and the filter plate are of an integrated packaging structure and generate medium-wave infrared laser output. The laser radar generates medium-wave infrared laser output and emits the laser in a scanning mode, and multi-angle scanning of radar transmitting end signals is achieved.

Description

technical field [0001] The invention belongs to the field of laser technology, and in particular relates to an integrated mid-wave infrared laser radar transmitting device. Background technique [0002] Lidar is a radar system based on the principle of TOF to emit laser beams to detect the position, speed and other characteristic quantities of the target. It is widely used in military and civilian fields. The application of lidar in the field of intelligent driving has great potential, but it is difficult to be widely used due to many unsolvable technical problems. There is interference from the monitoring system; the laser may cause harm to human eyes when used; it is easily interfered by sunlight. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an integrated mid-wave infrared laser radar transmitter to solve the problems that the existing laser radar easily interferes with the monitorin...
