High power laser diode driver provides pulsed current
IXYS Corporation has announced the introduction of the PCX-6425 high power laser diode driver/current source by its IXYS Colorado division. This instrument provides precision pulsed current with accurate microprocessor-based digital power control.
The PCX-6425 is an air cooled, bench top high power current source designed to drive laser diodes, bars and arrays at up to 150A of current and 120V maximum forward voltage. Pulse widths are adjustable from 100 microseconds to 5 milliseconds with pulse repetition rates from single shot to 100Hz. With variable output current and voltage, the PCX-6425 is ideal for research, laboratory, scientific and industrial applications.
The PCX-6425 may be operated through its intuitive front panel controls. The display provides immediate visual confirmation of all operating parameters, including output voltage, pulsed cur¬rent set points, and error/fault messages.
For automated applications, complete control of the instrument is provided through RS-232 or USB computer interfaces.
Conveniently located front panel BNC connector allows the PCX-6425 to be externally triggered. The current monitor and voltage monitor are also located on the front panel utilizing a BNC connector for each.
The laser diode is connected to the front panel of the PCX-6425 through a low-impedance twisted pair cable designed to preserve the fidelity of high-speed current pulses.
