Depressed cladding waveguides in a Dy:YAG crystal were fabricated by femtosecond direct laser writing. Their μ-luminescence characterization in the visible revealed well-preserved emission properties in the core region, a strong material modification within the damage tracks, and an anisotropic stress field associated with ear-like side structures. The developed waveguides are promising for yellow lasers.
