In this episode of the laser series I am showing some updates and ideas for the constant current laser, that were inspired by you! One particularly interesting idea is to control the efficient DC-DC converter with an op-amp, eliminating inefficient linear regulation completely. But before the drivers can be tested I have to fix the termination of the optical fibers. Those were burnt and unusable. Even when tediously lapping the fibers manually, some special equipment was neccessary:
