Passive mode-locked Yb fluorozirconate glass waveguide laser

Abstract

We report on the latest results towards a compact ultra-high repetition rate Yb-doped fluorozirconate laser, based on a simple and robust extended cavity design. Preliminary results show a laser operates with a pulse width of 2.5 ps and a repetition rate of 276 MHz at λ = 1018 nm. By controlling the dispersion and intracavity loss it should be possible to decrease the pulse width and increase the repetition rate to multi-GHz range.
