New product is Japan's first QCL for continuous wave operation at room temperature. Key benefits include higher stability and higher output than before, plus suitability for mass production. Intended for ultra-trace gas measurement systems in the mid-infrared region.
Hamamatsu, Japan – August 30, 2007 – Hamamatsu Photonics K.K. has developed the first single-wavelength quantum cascade laser (QCL) in Japan to achieve continuous wave operation at room temperature. Compared to its predecessors, the new QCL offers higher stability and higher output, and is more suitable for mass production. These factors should help the designers of mid-infrared ultra-trace gas measurement systems to make their instruments more compact and portable, and less expensive. The QCL is expected to contribute to industrial applications such as real-time monitoring of environmental
gases and the control of semiconductor process gases. Samples of the QCL will be available from September 1, 2007 to Japan-based as well as international manufacturers of analytical instruments. Production release is currently scheduled to begin on January 30, 2008.
In terms of exhibits, the new QCL will be shown at
FLAIR (Field Laser Applications in Industry and Research) 2007, an international conference for laser spectroscopy, in Florence, Italy from September 2 to 7. It will also be on display at the 68th Autumn Meeting of the Japan Society of Applied Physics (JSAP) at the Hokkaido Institute of Technology in Japan from September 4 to 8. A paper on the technology of the new QCL will be presented at the 68th Annual Meeting of the JSAP on September 7, and then again at the 20th Annual Meeting of the
IEEE Lasers and Electro-Optics Society (
LEOS Annual 2007) in Florida, U.S.A. on October 25.
