DEI offers a variety of laser diode driver instruments designed with the laser researcher, system designer and scientist in mind.
In both bench-top and rack-mount configurations, as well as a variety of compliance voltages and pulse configurations allow for a range of applications including both single diode and diode arrays as well as non-laser applications requiring a current source.
These instruments are a cornerstone of the early development for customers who take advantage of our Lab to Launch program for specific requirements and are perfect for burn-in, characterization and scientific installations.
Precision Pulse Control
The PCX-7500 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 450 A. The compliance voltage is dependent on the model of system. The pulse width is adjustable between 4 μs to 5,000 μs. The pulse repetition rate is 8 Hz to 10,000 Hz.
Ease of Setup and Operation
The PCX-7500 may be operated through its intuitive front panel controls. The color QVGA LCD provides immediate visual confirmation of all operating parameters, including pulsed current set points, internal trigger pulse width, internal trigger frequency, and error/fault messages.
Complete System Integration
For automated applications, complete control of the instrument is provided through RS-232, USB and Ethernet computer interfaces. 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 PCX-7500 through a low-impedance strip line cable designed to preserve the fidelity of high-speed current pulses. The output connector is interlocked so that the PCX-7500 is disabled when the connector is removed.
Internal or External Triggering
Conveniently located front panel BNC connectors allow the PCX-7500 to be externally triggered and synchronized for specialized interconnected equipment applications. The input impedance of the trigger 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 trigger.
