Ultrafast fibre vs tuneable ultrafast lasers: A comparative study

Chromacity Ltd has published a comprehensive report detailing the advantages and differences between ultrafast fibre lasers and tuneable ultrafast Ti: Sapphire lasers, highlighting key features relevant to research and industry applications.

Ultrafast fibre lasers, a type of solid-state laser, offer significant benefits, such as ultrashort pulse duration, high peak power, and excellent beam quality. One of their main strengths is their optical efficiency, which leads to a more compact design, making installation and operation simpler. In contrast, traditional tuneable ultrafast laser systems often require cooling mechanisms like water-cooled gain crystals. This cooling can be complex, utilising either active chillers or closed-loop systems to manage the heat generated by the high-power source.

Fibre lasers are less prone to thermal sensitivity and external disturbances compared to their tuneable counterparts, making them more versatile for experimental setups. The flexibility of the optical fibres used in these lasers enables customised configurations, optimising their performance for specific experiments.

Tuneable high-power lasers emit coherent light over a wide range of wavelengths, making them ideal for applications that demand wavelength flexibility and optimisation. While tuneable lasers offer adaptability across various wavelengths, fixed-wavelength fibre lasers present a cost-effective, technically efficient, and user-friendly alternative when such flexibility isn’t required.

This report provides valuable insights for researchers and industries aiming to choose between ultrafast fibre and tuneable ultrafast lasers based on their unique needs. Download your copy of the report now.
