摘要	This paper presents the design method and test results of a 910 nm high peak power vertical-cavity surface- emitting laser (VCSEL) array. More than 2 W output power was achieved for 910 nm VCSEL array under the Quasi-CW driving current. Under the electric pulsed driving condition with a repetition frequency of 10 kHz and a pulse width of 30 ns, the peak output power of a single VCSEL array reached 25.5 W at 60 A operating current. With the increase of operating current, the laser spectrum outputted by VCSEL array shows obvious broadening phenomenon, which proves that the large current drive of VCSEL array will still produce serious internal thermal effect even at the operation of narrow pulse. When the driving current increases to 60 A, the pulse width of the laser pulse waveform of VCSEL array only widens by about 6 ns. This proves that VCSEL array has A very superior impulse response characteristic. After beam collimation of VCSEL array, nearly circular uniform spot was obtained at a distance of 1 m. We believe that this kind of high power 910 nm array light source has great application potential in the future intelligent driving fields such as vehicle light detection and ranging (LiDAR). 2019, Science Press.
