PCM-7510 Pulsed Current Source
Precision Pulse Control The PCM-7510 is an air-cooled, high-power current source designed to drive laser diodes, bars, and arrays. The output current can be set from 10 A to 250 A. The pulse width is adjustable between 5 µs to 5,000 µs. The internal pulse repetition rate is 40 Hz to 6,000 Hz. Ease of Setup and Operation The PCM-7510 may be operated through its intuitive front panel controls. The color touch screen provides immediate visual confirmation and control of all operating parameters. Complete System Integration For automated applications, complete control of the instrument is provided through RS-232 computer interface. Up to four system configurations may be stored in internal non-volatile memory, providing instant recall of frequently-used configurations. Low Inductance Output Cable The laser diode is connected to the PCM-7510 through a low-impedance stripline cable designed to preserve the fidelity of high-speed current pulses. Internal or External Gate Conveniently located front panel BNC connectors allow the PCM-7510 to be externally triggered and synchronized for specialized interconnected equipment applications. The impedance of the gate input is selectable to either 50 Ω or 10,000 Ω. The synchronization output pulse is synchronized to the leading edge of the output current pulse and is active with internal or external gate.
External Power Supplies The PCM-7510 requires two user-supplied power supplies, a +24 V DC and a High Voltage Power Supply. The output current is derived from the high voltage power supply which is connected to a large capacitor bank inside of the instrument. Ordering Information PCM-7510 Module

Notes
SYNC Output signal follows the internal or external trigger by about 5 ns to 15 ns. This signal coincides with the signals that start the output pulse. The SYNC Output goes from 0V to 5V as soon as the output stage starts to drive the output and falls from 5V to 0V as soon as the system turns off the output pulse. This signal can be used to run multiple systems in parallel by calibrating the external trigger pulses it account for variation in timing within the instrument.Warranty—One year parts and labor on defects in materials and workmanship.
The PCM-7510 current source meets or exceeds these specifications. All specifications are measured with a low inductance strip line interconnect cable to the laser diode.

Safe Operating Area
The “HVPS Voltage SOA” graph shows the full range of adjustability for the HVPS that is set based on the forward voltage of the laser being driven. Operation of the instrument outside of this range can result in permanent damage to the instrument, laser or both.
The graph above shows the maximum output power of the instrument for all HVPS voltage settings. Operation of the instrument above the graphed limit can result in permanent damage to the instrument, laser or both.
