Researchers from VTT Technical Research Centre of Finland have developed optical interruption of a Mid-IR QCL using a near-infrared (NIR) laser diode for cavity ring-down spectroscopy (CRDS). The QCL is modulated from the injection of the NIR laser diode, and this shifts the frequency of the signal in the cavity generating rapid interruption of the high-finesse cavity resonance. Optical interruption reduces the high bandwidth requirements of the QCL driver as well as lowers cost and complexity of the system. The necessary precision control was provided by Wavelength Electronics’ LDD200P and QCL1000 drivers.
Laser diodes are used in a variety of applications, each utilizing the unique properties of semiconductor lasers. Creating effective systems can be complicated, but well worth the effort of optimization.
Application Note AN-LD18: Optimizing Laser Diode Control provides a practical step-by-step guide to optimizing laser diode control with rule of thumb approximations that work with most laser diodes. It demonstrates recommended operating techniques for optimum results.
In Star Trek lore, April 5, 2063 is the day that humans make first contact with Vulcans, as depicted in the movie Star Trek: First Contact.
The Extraterrestrial Tourism Council wants to invite you to consider the wonders of Bozeman, Montana. In a video released on Monday, April 5 to celebrate First Contact Day, Star Trek highlights the reason why life in Bozeman would be appealing to extraterrestrial life forms.
