摘要

利用2 μm波段分布式Bragg反射激光器构建了用于二次谐波探测波长调制光谱的线性波长扫描系统。利用我们设计的锗标准子滤波器线性度评价方法，实验证明了激光的非线性度可以得到有效补偿。

Linearizer for wavelength sweep at tunable DBR-LD and linearity evaluation of sweep

We constructed the linear wavelength sweeping system with 2-μm-band distributed Bragg reflector laser for the second-harmonic-detection wavelength modulation spectroscopy. Using our devised linearity evaluation method with a germanium etalon filter, we experimentally confirmed that the nonlinearity of the laser can be efficiently compensated.
