Application Note: Impedance of Laser Diodes and inductive behaviour

Impedance of Laser DiodesInductive behaviourRelated Products: LDP-AV, LDP-V, LDP-CL   The parasitic stray inductive behaviour is the most important influence on the pulse rise time. The output voltage of the driver must be able to charge the…

Why is does the current deviate from my set current after a calibration with a PLCS-21 and a compatible LDP-V driver?

Why is does the current deviate from my set current after a calibration with a PLCS-21 and a compatible LDP-V driver? The calibration process is carried out by ramping up the high voltage (HV) from the user definied minimum value to the maximum…

Why does my LDP-C/CW 18/40/50-05 driver does not reach the full current of my external applied setpoint?

Why does my LDP-C/CW 18/40/50-05 driver does not reach the full current of my external applied setpoint? This driver series features a potentiometer which can be used to limit the maximum current in order to protect the laser diode. Please refer to…

My PicoLAS short pulse driver (e.g. from the LDP-V series) does not generate any output when I send a trigger signal. What should I check?

My PicoLAS short pulse driver (e.g. from the LDP-V series) does not generate any output when I send a trigger signal. What should I check? Please follow the “How get started guide” in the manual. If not stated differently, please always start with…

Can I use a PLCS-21 pulse generator for a driver with an analog signal input such as a LDP-VRM 01-12 CA?

Can I use a PLCS-21 pulse generator for a driver with an analog signal input such as a LDP-VRM 01-12 CA? The PLCS-21 is a digital pulse generator and only generates a 5 V high signal apart from its 0 V low state. Thus, it is not suitable for…
