JMAR Delivers UV Laser to NASA

SAN DIEGO, Feb. 9, 2010 – JMAR LLC, laser-based product solutions designer specializing in microbiological detection of organisms in water, environmental gas emissions and explosives detection, announced it has developed a dual wavelength UV Dial transmitter for atmospheric Ozone research.

Historically, accessing the UV band needed for Ozone Dial has been mainly achieved through frequency doubling liquid dye lasers or Raman shifting in high pressure hydrogen. Tunable OPO systems have existed for years, but are large, complex, inefficient, and typically low rep-rate.

“We are pleased to bring together our resources, expertise, and the flexibility of our OPO technology to produce cutting edge products that allow critical research to move forward in the field of Atmospheric Ozone Monitoring,” said Dave Wessing, president and CEO of JMAR.

The current JMAR system is designed specifically to access the 290-300 nm range required for Ozone Lidar measurements and evaluation of pollution from the ground to the atmospheric boundary layer. With the JMAR nonlinear optical approach used in this system, many other wavelength pairs can be achieved for virtually any Dial measurement. Two fixed frequency OPOs are set up and their outputs are then mixed with the pump laser harmonic wavelengths to achieve the required Dial wavelengths.

GLOSSARY
lidar
An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
