Abstract

We are developing a 10W-level tunable fibre laser source with a simple design. The source serves dual purposes: firstly, it enables the exploration of how altering pump wavelengths affects the efficiency of 3.5 micron, dual-wavelength pumped mid-infrared fibre laser systems. Secondly, it facilitates the investigation of the exact absorption coefficients of optical materials relevant to the LIGO gravitational wave observatory. This technology holds promise for advancing knowledge and enhancing the sensitivity and precision of gravitational wave detection, our latest results will be presented.
