Ultra-fast LiDAR driver delivers 480W peak power
In partnership with Osram Opto Semiconductors, GaN Systems has developed an ultrafast laser driver with a high-power, multi-channel SMT laser for LiDAR (Light detection and ranging) systems.

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 one nanosecond pulse rise time, while driving all four channels at 40A each to deliver 480W 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.
