High Power ns-Pulse VCSEL Driver Board
High Power ns-Pulse VCSEL Driver Board
Conventional external signal generators cannot deliver the nanosecond-pulse drive currents required by LiDAR systems.
Raysees solves this with an integrated proprietary pulse generation circuit — no external signal generator needed —
capable of producing drive currents up to 40 A with nanosecond-level pulse widths.
A single driver board supports multiple VCSEL package formats, enabling nanosecond narrow-pulse
driving of multi-junction high-power VCSEL chips.
Accelerate your LiDAR product definition and hardware bring-up — faster and simpler.
Two operating modes are available:
Constant Voltage Mode and Capacitor Discharging Mode.
