Drives Quantum-Cascade Lasers and Other Laser Modules
BOZEMAN, Mont., March 4 -- ILX Lightwave, a maker of laser diode instrumentation and test systems, today announced the introduction of the LDX-3232 high-compliance laser diode current source, what the company says is the industry’s only laser diode driver designed specifically for controlling high-compliance voltage devices such as quantum-cascade laser diodes.

The design, based on precision current-source technology developed at ILX Lightwave, allows the LDX-3232 to deliver up to 4 A of low noise current at up to 15 V with a stability of better than 20 ppm. The company says this performance is critical for spectroscopic applications such as development of new quantum-cascade laser-based sensors for gas analysis. The LDX-3232 also includes fourth-generation laser diode protection technology developed by ILX and a new over-temperature sense input for protecting expensive quantum-cascade lasers.

According to ILX, the need for the LDX-3232 became apparent through interviews with scientists and engineers who use quantum-cascade laser diodes in their research and development of optical sensors. According to Thaddeus Orosz, ILX Lightwave instrumentation product manager, “The use of CW quantum-cascade laser diodes in optical sensors is a relatively new technology which is being used to meet the growing need for economical, portable gas sensors used in environmental, military and security applications. We’re very pleased to provide a solution to meet the market’s growing demand for a current source designed specifically for quantum-cascade lasers. It’s exciting to know that we’re at the forefront of this technology.”
