Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application note is intended to briefly address this topic ...

The new laser diode driver iC-HT permits microcontroller-based activation of laser diodes in CW mode. With this device laser diodes can be driven by either the optical output power (using APC), the ...

Little Laser Trip Wire circuit presented here can detect movement of people or objects while passing through the laser beam and trigger security alarms as alert signals to those concerned. What is ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).
