The (fictitious) startup company Bedrock Phototonics will be releasing in the next year or two high power fiber lasers that involve semiconductor diode lasers as the initial source of light. the light from these sources is used to excite custom optical fiber in order to produce the laser emission. This project will involve setting up the electronics and computer interfacing of an original equipment manufacturer (OEM) high power diode laser current driver device that is capable of 100A and 6V output. once operating, the driver will be connected to 30W and 80W fiber-coupled diode laser for testing. The project will build the necessary software to run the current driver continuously. The project is a combination of Photonics and Electronics to make a professional Continuous Wave Current Driver which can be used to operate any kind of diode laser. The project includes safety switches, temperature control of the current driver and diode laser and variable output power. Theis project will discuss all the circuits which have been designed specifically for this control system and it has the potential to improve in the future.
