英文摘要	A system for controlling the operation of multiple laser diodes in a noise free and efficient manner. The system includes a control module that generates control signals to control and regulate the multiple laser diodes, and an input/output module that allows control parameters to be selected and set by a user. Each individual laser diode is stabilized and regulated by its own individual laser diode driver module that includes current, power, and temperature regulation systems to ensure the operating parameters of each laser diode are accurately maintained. Each laser diode driver module also measures key operating parameters to allow the control module to monitor system operation and switch malfunctioning diodes off. All analog-to-digital conversions of each diode's operating parameters are performed by digital circuitry within the control module, which is physically separated from the laser diode driver modules to minimize interference that is typically caused by the digital switching. To further minimize digital switching interference, all digital portions of each laser diode driver module transmit digital signals on a different layer within the laser diode driver module that analog signals are transmitted on.
