What is the difference between CW mode and pulse mode for laser diode drivers?
What is the difference between CW mode and pulse mode for laser diode drivers? CW operation in laser diode drivers stands for continuous wave, i.e. continuous operation of the laser diode with a constant current. The constant current means that…
What is a laser diode driver?
What is a laser diode driver? To make laser diodes or LEDs light up, they must be supplied with current. LEDs and laser diodes are current-driven components, as the luminous flux is almost proportional to the electrical current. The…
Application Note: LDP-V xx-100 with the PLCS-21 and PLB-21
Application Note: LDP-V xx-100 with the PLCS-21 and PLB-21 Associated products: LDP-V 03-100, LDP-V 50-100, LDP-V 80-100, LDP-V 240-100, PLCS-21, PLB-21, LDP-V Kit This application note briefly describes how to connect a PLB-21 to various laser…
Application Note: Laserdiode-Connections
Application Note: Laserdiode-Connections Related Products: All PicoLAS short pulse driver The connection of the laser diode to any of the PicoLAS short pulse drivers is very critical. A wrong connection, the wrong decision about the connection…
Application Note: Impedance of Laser Diodes and inductive behaviour
Impedance of laser diodes Inductive behaviorAssociated products: LDP-AV, LDP-V, LDP-C The parasitic inductive behavior is the most important influence on the pulse rise time. The output voltage of the driver must be able to charge the leakage…
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…
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…
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, the PLCS-21 is not suitable…
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? 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…
