On the Characteristics of Pulsed Laser Driver Based on RLC Oscillation
The laser driver circuit is very important in time-of-flight lidar. Its performance directly affects many key system parameters such as detection range
signal-to-noise ratio and false alarm rate. This article innovatively introduces appropriate inductance in charging circuit
forming resistance
inductance and capacitance(RLC) second-order differential oscillation circuit
which can greatly increase the driving voltage of the pulse laser and thereby increasing the driving current that drives the laser to produce high-power
narrow-pulsewidth laser. Theoretical calculations
numerical simulations and experimental verification show that driving current of pulse laser can be increased for over 85%
and the output power is increased for over 114% as an appropriate inductor is introduced into the system.
