【摘要】 本文采用掺铒光纤环腔激光器构建了一种能实现准分布式测量的红外气体传感器,研究了泵浦功率与系统损耗对激光输出功率、信噪比和波长调谐范围的影响,探究了气体传感灵敏度的增强方法。以乙炔为例,得到了26条吸收谱线的位置和吸光度,实现了传感检测。更多还原

【Abstract】 An Infrared gas sensor based on erbium-doped fiber laser,which can realize quasi-distributed measure,is developed in this dissertation.Study has been done in experiments to research the relationship between system parameters(pump power,cavity loss)and laser characteristics(output power,signal to noise ratio,spectrum range),as well as how to improve the sensitivity enhancement factor.As an application of gas sensing,the peak locations and absorbance coefficients of 26 transition lines of acetylene are measured.更多还原
