Osram Opto Semiconductors unveils an ultrafast laser driver with a high-power, multi-channel Surface Mount (SMT) laser for light detection and ranging (LiDAR) systems. Osram and GaN Systems partnered to develop the breakthrough in laser driver technology that enables longer range and higher resolution LiDAR architectures.
One of the issues with LiDAR technology has been its inability to transmit lasers at short pulses, while maintaining high peak power, which is necessary to ensure that the LiDAR is eye safe with a long range and high resolution. To address this need, Osram worked with GaN Systems to develop a laser driver with a 1-ns pulse rise time, while driving all four channels at 40A each to deliver 480W of peak power. This peak power then can be modulated at low-duty cycles to produce high resolution 3D cloud points at long range for new LiDAR designs.
