| Outline of Final Research Achievements |
Gas detection system for the purpose of preventing explosion accident has been developed. Simultaneous detection of oxygen and acetylene using a single diode laser in conjunction with a nonlinear optics is achieved. Effect of nonlinear optics on wavelength modulation method is investigated and shown that the condition which maximizes signal to noise ratio differs from the wavelength of highest conversion efficiency. The signal response time is less than 1s which is faster than any other conventional gas detection methods.
