Cavity Structure

We demonstrate a mid-infrared (MIR) wavelength-tunable high-power single-longitudinal-mode (SLM) fiber laser using a compound cavity structure. The compound cavity consists of an Er-doped ZBLAN fiber perpendicularly cleaved at two-ends and an external cavity formed by a fiber end-face and a narrow bandwidth ruled reflective diffraction grating. SLM operation is achieved through the combined effects of the narrow bandwidth grating and the compound cavity. By rotating the grating, the laser wavelength can be continuously tuned over 100 nm from 2705 nm to 2806 nm with the SLM operation maintained. High output power up to 450 mW is achieved under the SLM regime.

AbstractDevelopment of novel mid-infrared (MIR) lasers could ultimately boost emerging detection technologies towards innovative spectroscopic and imaging solutions. Photoacoustic (PA) modality has been heralded for years as one of the most powerful detection tools enabling high signal-to-noise ratio analysis. Here, we demonstrate a novel, compact and sensitive MIR-PA system for carbon dioxide (CO2) monitoring at its strongest absorption band by combining a gas-filled fiber laser and PA technology. Specifically, the PA signals were excited by a custom-made hydrogen (H2) based MIR Raman fiber laser source with a pulse energy of ⁓ 18 μJ, quantum efficiency of ⁓ 80% and peak power of ⁓ 3.9 kW. A CO2 detection limit of 605 ppbv was attained from the Allan deviation. This work constitutes an alternative method for advanced high-sensitivity gas detection.
