摘要：
The linewidth of a gallium antimonide-based laterally-coupled 2.05 mu m DFB laser emitting 40 mW of power at 9 C is measured. The measured linewidth is 1.7 MHz for 500 ms and 1.4 MHz for 10 ms observation time, respectively. The combination of high power and low frequency jitter makes this laser useful for detecting CO2 in air in both in-situ and remote sensing applications. The linewidth measurement is also discussed.
