The first solid-core fiber laser was demonstrated in 1962, shortly after the first laser was demonstrated. Although the prospect of having a waveguide laser was exciting, it wasn’t until fibers started being used for optical communication networks that fibers in optics really took off. Fiber laser systems are also seeing more attention in recent years because while they lag in achievable energies compared to Ti:Sapphire lasers, they can support much higher repetition rates and can be compressible down to femtosecond durations, making fiber lasers with their high peak and average powers a great contender for next generation particle accelerators. Look at some of the pages below for some greater insight into the basics of fibers before heading to the next sections!
