| Zusammenfassung: | A method and apparatus for driving a laser diode source, such as a laser diode or a laser diode array. The driver controlling current in response to a signal indicative of excessive current or current density. The signal may be derived from the drive current, the voltage across the laser diode source or the impedance of the laser diode source. The circuit may be pulsed using a switch, such as a GCT. The current to generate drive the laser diode source provided by a capacitive or inductive charging circuit. |
