The application range of lidar is wide. The downstream application market of Lidar in China mainly focuses on unmanned driving and exploration and mapping. Lidar is used in the field of unmanned driving, which can identify obstacles and ensure driving safety. With the booming development of unmanned driving market, vehicle lidar market develops rapidly. In 2016, the market size of China's vehicle-mounted lidar was 193 million yuan, and in 2017 it was 277 million yuan, with a year-on-year growth of 43.52%, showing a state of rapid growth. It is expected that by 2020, the market size of China's vehicle-mounted lidar will break through 500 million yuan, reaching 529 million yuan. As one of the important sensors in unmanned driving technology, vehicle laser radar has a broad development prospect. The lidar market for automotive and industrial applications is expected to reach $5.7 billion by 2026, with a compound annual growth rate of 21% between 2020 and 2026, according to YOLE.
In addition to vehicle-borne unmanned driving, lidar technology in mapping, exploration, as well as unmanned aerial vehicles, service robots and other fields are rapidly improving, the demand for lidar will maintain a rapid growth trend. In particular, with the development of unmanned driving, surveying and mapping, and other applications, the test range and accuracy of lidar has put forward higher requirements, which requires higher power laser transmitter chip, in view of this, Shenzhen Raybow Opto launched 6 w/w / 20 w / 40 w / 50 w / 75 w / 100 w / 140 w series 905 nm pulse laser chip.
The 905nm pulsed laser emitting chip belongs to EEL side emitting chip and supports single, triple and quadruple emitting nodes. The photoelectric conversion efficiency is 41%. Fast axis divergence Angle 30 degrees, slow axis divergence Angle 13 degrees. In particular, it is worth noting that this series of chips have excellent high temperature resistance, with a power reduction of 4% for every 10℃ increase in the test weight between 25℃ and 125℃, and has passed the stringent AEC-Q102 certification test.
Large-scale commercial lidar is just around the corner. The localization of laser chip will effectively help customers reduce costs and improve cost performance, and also have the advantages of short delivery time and fast service response. In the future, Raywave optoelectronics will closely meet the market demand and develop more new products (low divergence Angle, low temperature drift, etc.).
