Abstract

In this paper we report on various new aspects, which were achieved by writing waveguides in Pr:SrAl₁₂O₁₉ with fs-laser pulses. To the best of our knowledge we could demonstrate for the first time: An active dielectric crystalline waveguide laser in the visible spectral range, a Pr³⁺ based channel waveguide laser and the writing of waveguides into SrAl₁₂O₁₉ by fs-laser inscription. Furthermore we have demonstrated GalnN-diode pumping of this waveguide laser.
