The LDX-3232 High Compliance Laser Diode Driver is the industry's only laser diode driver specifically developed for controlling high compliance voltage devices such as quantum cascade laser diodes. Careful attention to design allows these drivers to deliver up to 4A of low noise current at up to 15V with a stability of better than 20ppm. This performance is critical for development of room temperature quantum cascade lasers and spectroscopic applications using quantum cascade lasers. In addition to precision current control, the LDX-3232 is loaded with standard features such as dual current ranges, constant power control, fine/coarse set point control, laser current and voltage measurement, photodiode current display modes, forward voltage adjustment and measurement, and an external modulation input.

Furthermore, all of ILX Lightwave's proven laser diode protection strategies have been designed into each model including slow start, adjustable current limits and compliance voltage, intermittent contact protection, and shorting relays. In addition, the LDX-3232 accepts a TTL input that can be configured to turn off the output to the laser diode in an over-temperature condition.

Remote operation in an R&D or production environment is afforded through the GPIB/IEEE-488 interface and a TTL output trigger. For virtual instrument programming, LabVIEW® instrument drivers are available free of charge. LabVIEW® instrument drivers can be downloaded from the Literature and Downloads tab on this page.

LDX-3232高柔度激光二极管驱动器是业界唯一专门为控制高柔度电压器件(如量子级联激光二极管)而开发的激光二极管驱动器。对设计的谨慎关注使这些驱动程序能够提供高达4A的低噪音电流，最高可达15V，稳定度超过20ppm。这种性能对于开发室温量子级联激光器和使用量子级联激光器的光谱应用至关重要。除了精密电流控制外，LDX-3232还具有双电流范围、恒功率控制、精/粗设定值控制、激光电流和电压测量、光电二极管电流显示模式、正向电压调节和测量以及外部调制输入等标准特性。

此外，所有ILX光波的已被证实的激光二极管保护策略都被设计到每一个模型中，包括慢启动、可调电流限制和柔度电压、间歇接触保护和短路继电器。此外，LDX-3232接受TTL输入，可以配置为在超温条件下关闭激光器的输出。
