摘要: 为了研发一种应用于CO2探测激光雷达的全光纤宽带可调谐高功率光源,以CO2的超精确吸收谱为基础,结合外腔可调谐激光器和L波段光纤放大器,进行了理论分析和实验验证,取得了针对1572nm附近吸收峰的连续调谐窄线宽光源的数据,并通过铒镱双包层光纤放大器将输出光功率提升到瓦级以上。结果表明,光源输出功率大于10dBm,边模抑制比大于50dB,线宽500kHz左右,1572nm放大器最大增益可达25.13dB,输出光功率达到1W以上。该光源具有体积小、低功耗和低成本的优势,对实现更大范围的空间CO2浓度探测分析有一定的帮助。Abstract: An all fiber,compact high power tunable laser source for atmospheric CO2 measurement was investigated.Based on the ultra precise atmospheric CO2 absorption spectrum,a tunable seed laser was designed with the peak absorption around 1572nm,and then its output power was amplified to the order of watt level with an Er-Yb double cladding fiber amplifier.The experimental results show that the laser can provide 10dBm output power with 50dB side mode suppression,500kHz linewidth;the max gain of the fiber amplifier is 25.13dB,output power is 1W.This laser possesses a small size,low power consumption and low cost it builds a steady foundation for the wider range of Atmospheric CO2 measurements.
