Abstract:

The development of diode lasers for automotive LiDAR systems is presented. The lasers feature an internal Bragg grating for low wavelength shift with temperature and small spectral width and emit nanosecond pulses with peak powers >30 W (single-emitter) or >100 W (3-emitter chip) up to 85°C.
