A system includes one or more current sources configured to couple to an AC to DC power converter without a DC-to-DC converter between the current sources and the power converter. Each of the current sources includes a high voltage switch and one or more independent safety shutoffs. The one or more safety shutoffs are configured to disable emission of electromagnetic radiation from a laser module when triggered. A current source controller coupled to the safety shutoff(s) is configured to generate enabling signals that enable normal current source operation. The controller includes circuitry configured to measure power across the high voltage switch when the controller instructs the high voltage switch to turn off to determine proper operation of the safety shutoff(s).

High powered laser electronics

A laser system includes a high voltage AC-to-DC power converter and one or more current sources coupled to the power converter without a DC-to-DC converter between the current sources and the power converter. Each of the current sources includes a high voltage switch and one or more independent safety shutoffs. A laser module is operably coupled to the one or more current source and configured to emit electromagnetic radiation wherein the one or more safety shutoffs are configured to disable emission of electromagnetic radiation from the laser module when triggered. A current source controller coupled to the safety shutoff(s) is configured to generate enabling signals that enable normal current source operation. The controller includes circuitry configured to measure power across the high voltage switch when the controller instructs the high voltage switch to turn off to determine proper operation of the safety shutoff(s).
