| Abstract: | We employ the technologies of modulation and scan and the fact that a gas can absorb a certain wavelength laser to detect the second harmonic signal by a lock-in amplifier.Experimental results show that the approach has such positives as high sensitivity and long-term stability and can satisfy the requirements of gases detection. |

| Keywords: | gas detection spectrum absorption trace detection second harmonic waves |
