Abstract
For current 905nm pulsed laser diode(PLD) for LiDAR applications, most of them are single channel chips each with a power range of 75W-120W designed for scanning multiple single points. In this work, kilowatt 905nm light source based on eight channel 905nm PLD mini-bars had been designed and packaged using flip chip bonding technology. A series of kilowatt 905nm PLD modules were fabricated and characterized. The maximum output power of 982W limited by the pulse driver was obtained for the first time under the condition of 100V@5ns,100kHz at room temperature. The spectral width of FWHM and FW90%E was 5.1nm and 7.2nm, respectively. The far field divergence test data indicated that the fast axis divergence@1/e2 and slow axis divergence@1/e2 was 0.38°and 27.59°, respectively. In the future, the fast axis divergence@1/e2 and the slow axis FoV can be designed and optimized for any particular LiDAR system.
