The application range of lidar is wide, and the downstream application market of lidar is mainly concentrated in the field of unmanned driving and surveying and mapping. Lidar is used in the field of unmanned driving, which can identify obstacles and ensure driving safety. With the vigorous development of the unmanned driving market, the automotive lidar market has developed rapidly. As one of the most important sensors in driverless technology, vehicle-mounted lidar has broad development prospects.
In addition to vehicle-mounted unmanned driving, the technology of lidar in the fields of surveying and surveying, drones, and service robots is rapidly improving. The demand for lidar will maintain a rapid growth. In particular, with the development of applications such as unmanned driving and surveying and surveying, higher requirements have been placed on the testing distance and accuracy of lidar. This requires higher-power laser emission chips. BrandNew recently launched a newly developed 100W/150W 905nm pulsed lidar chip.
The chip uses a 4-layer light-emitting section with a light emitting size of 300μm x 16μm and a photoelectric conversion efficiency of 41%. The fast axis divergence angle is 30 degrees, and the slow axis divergence angle is 10 degrees. It is particularly worth noting that this chip is excellent in high temperature resistance. The temperature change test at 25 ° C to 125 ° C is heavy. For every 10 ° C increase, the power is reduced by 4%.
