MHz-repetition rate fs-laser-inscribed crystalline waveguide lasers inscribed at 100 mm/s: erratum

We present an erratum concerning the repetition rate of the fs-laser system used for the inscription of the waveguides stated in our paper [Opt. Express 28, 12011-12019 (2020)]. The Fidelity HP High Energy laser supplied by Coherent Inc. features a repetition rate of 10 MHz instead of the value of 1 MHz stated in the paper.
