For automotive light detection and ranging (LiDAR) systems diode lasers emitting short optical pulses with a good beam quality and a low wavelength shift over a wide operating temperature range is needed. In this paper, theoretical and experimental results of broad area laser diodes specially designed for this application are presented. Optical pulse powers of tens of watts and pulse lengths in the 10 ns-range for wavelengths near 905 nm and environmental temperatures between 15 and 85 °C are achieved. Due to the integrated Bragg grating the wavelength shift with temperature is as low as 65 pm K−1. The contact mesa with a width of 50 μm leads to a lateral M2 value of about 9. Streak camera measurements of the temporal evolution of the lateral near field intensity reveal that the highest intensity is emitted near the mesa edges. Simulation results of power current characteristics indicate that the power saturation experimentally observed can be attributed to nonlinear effects such as two-photon-absorption and gain compression.
