چکیده انگلیسی
Narrow line-width fiber lasers are useful in gas-sensing, but systems that are both tunable and stable are rare. Here, we describe a single-wavelength ring cavity erbium-doped photonic crystal fiber laser (ED-PCFL) that can align the acetylene (C2H2) gas absorption peak with high precision and a maximum deviation less than 0.012â¯nm. Rather than using a combination of erbium-doped fiber and a strong nonlinear fiber, ED-PCF was used as a gain medium to achieve a stable single-wavelength output based on the non-linear polarization rotation effect (NPR). This was selected because ED-PCF has a strong nonlinear effect. We added the dual polarization controllers (PCs) to weaken the homogeneous broadening based on the traditional tunable filter (TF) filtering structure. The results show that these steps improve the tunability of the laser wavelength and enhance the stability of the light source. The final laser had a side-mode suppression ratio as high as 60â¯dB over 45â¯nm with a maximum fluctuation in wavelength less than 6â¯pm. The peak power standard deviation was â¼0.03â¯dB during the 2â¯h experimental time. The peak power response of ED-PCFL was studied as a function of C2H2 concentrations, and the calculated R-squared value was 0.993. This means that the ED-PCFL is suitable for C2H2 sensing.
