Technical Field/Operating Unit or Centre:

CSIR National Laser Centre

Business Opportunity:

This technology is available for licensing to interested parties, as a partnering opportunity, an investment opportunity in a start-up, or as an investment opportunity in further technology development. Depending on the needs of the client this technology can also be customized to fulfil their requirements.

Technology description (summary):

Over the past ten years the NLC has developed unique skills in mid-infrared laser sources as well as novel resonator concepts due to several large and focussed research and development programmes, combination of skills and expertise in diode pumped solid state (DPSS) lasers, laser beam propagation and resonator development. This has resulted in the development of several unique laser systems and resonator architectures that have delivered world records in several parameter categories in the MidIR wavelength region. The mid-infrared spectral region of 2-5μm contains strong characteristic vibrational transitions of many important molecules as well as two atmospheric transmission windows of, which makes it crucial for applications in spectroscopy, materials processing, chemical and bio-molecular sensing, security and industry.
