Ultra-fast lasers are key to wide range of new and developing technologies, from microscopy and micromachining through to quantum encrypted communications. The use of glass as the gain material in ultra-fast laser systems offers a number of advantages over crystalline laser gain materials in terms of both cost and compositional flexibility.
Through the Innovate UK funded ‘ULTRA-Glass’ project Glass Technology Services Ltd and Vitritech Ltd have produced new glass materials that can be used as gain material in 1000nm and 1500nm mode-locked laser systems, incorporating rare-earth dopants (Er3+, Yb3+ etc) into an optimised phosphate glass system.
This talk will share the developments made over the course of the ULTRA-Glass project, the various material options considered and will share the some of the initial results on the performance of the developed glasses in mode-locked laser cavities.
