Methane sensing at 1300 nm band with a hollow core photonic bandgap fiber as gas cell
The feasibility of employing a hollow-core photonic bandgap fibre (HC-PBF) to measure methane concentrations below its lower explosive limit is assessed. Using a 5.6 m-long HC-PBF as gas cell, the spectrum of methane at v2 + 2v3 band at 1300 nm has been recorded and the Q-branch at 1331.55 nm select...
