The design of this laser driver circuit has already been simulated and a prototype has been built. The individual parts of the circuit have been successfully tested, only the current regulation is still faulty. The calculated voltage range for controlling the Mosfet is not sufficient, since its characteristics in the saturation range deviate significantly from the data sheet in reality. Here is another way to manually adjust this voltage to the respective Mosfet the therefore necessary filter and voltage stabilization circuits have to be added to the design in the next Iteration.
