Block Engineering Releases Ultra-Miniaturized Quantum Cascade Laser Products

MARLBOROUGH, Mass., Jan. 28, 2014 /PRNewswire/ -- Block Engineering, the leader in Quantum Cascade Laser (QCL) instrumentation, announced today the release of two ultra-miniaturized QCL products, the Mini-QCL (TM) Module and the new LaserTune (TM) Infrared Source. The Mini-QCL is a widely-tunable QCL module for Original Equipment Manufacturers (OEMs), weighing only 75 grams (~2.5 oz). Block's next-generation LaserTune has been miniaturized to a compact (16.5 × 12.7 × 11 cm), wirelessly-controllable system, while offering the widest contiguous tuning range available on the market (greater than 1000 cm-1).


Scott Riggi, VP of Sales, commented, "We are receiving tremendous interest in these new products from universities, corporate R&D labs, and a wide range of OEMs. Block has now introduced the world's most compact, full-function QCL source with the widest contiguous spectral tuning range. The demand for these devices in gas sensing, metrology, and academic and corporate R&D applications is significant."

Petros Kotidis, Block's CEO added, "These two new products are the result of Block's innovation spirit, engineering strength, and optical packaging capabilities. They meet a strong market need for ultra-compact, ultra-widely tunable sources for OEM integration and all-in-one laser sources. These devices are now enabling new applications, which were not available to the past generations of QCLs, due to size, ruggedness and performance limitations. I look forward to the adoption of these new devices by our customers and the rapid growth of their applications."

The Mini-QCL Module is available in spectral ranges greater than 250 cm-1 per module, and multiple modules can be combined by OEMs. The module can be used in a wide variety of real-time gas analysis applications requiring a mid-infrared laser source, including greenhouse gas monitoring, automotive combustion analysis, oil and gas exploration, and air quality monitoring. The module is also designed to be integrated into a variety of spectroscopic instruments, including products used in the fields of Photoacoustic Spectroscopy (PAS), Cavity Ring-Down Spectroscopy (CRDS), Infrared Microscopy, and Atomic Force Microscopy (AFM).                                             

The New LaserTune Infrared Source has been significantly reduced in size, while leading the industry in contiguous tuning range. The 2x4 mm collimated beam can now be programmed to operate in several modes with a manual step, programmable step, and programmable sweep. The LaserTune offers fast scan capability at 25 cm-1 per msec, and the source can be programmed to emit pulses from 20 to 500 nsec, while maintaining a duty-cycle up to ~30%. Computer control of the LaserTune is via Wireless or Ethernet/HDMI with analog and digital control for monitoring and controlling the laser wavelength.

Block will be demonstrating the products at SPIE's Photonics West Conference (Booth #5333) and the BiOS Conference (Booth #8507) in San Francisco.

IT data is typically silo'd by the various tools in place. Unifying all the log, metric and event data in one analytics platform stops finger pointing and provides the end-to-end correlation. Logs, metrics and custom event data can be joined to tell the holistic story of your software and operations. For example, users can correlate code deploys to system performance to application error codes.
