Advances in doped optical fibre 2.0

High power fibre lasers have established their strong presence in the manufacturing sector and for scientific applications. The key to the power scaling of fibre lasers can largely be attributed to the progress in large-mode-area (LMA) fibre designs by offering a higher threshold to the non-linear effects and development of high performance rare-earth doped fibres. In LMA fibres, a guiding discrimination between the fundamental mode and higher-order modes can ensure an effective single-mode operation. In this talk, Professor Sahu will review the progress in rare-earth doped fibres suitable for efficient high power laser operation in the 1µm and 2µm wavelength regions.
