Abstract
A method for measuring concentrations of multiple gases by using an infrared band laser light includes: pumping Ho crystal by using a 1.9 μm single thulium-doped solid-state laser to obtain a 2 μm band near-infrared laser output; controlling a light-emitting angle of 2 μm band laser light; allowing the 2 μm laser light to enter a first measurement cell at a first emergent angle, and measuring a concentration of methane gas in the first measurement cell; generating and introducing the 3-5 μm mid-infrared laser light into a second measurement cell to measure concentrations of ammonia gas and carbon monoxide in the second measurement cell; generating and introducing the 6-12 μm far-infrared laser light into a third measurement cell to measure concentrations of carbon dioxide, acetylene, ethylene and ethane gas in the third measurement cell.
