Compact OP-VECSEL-pumped Er:Yb:YAB microchip laser with M2 < 1.5 at 1.55 µm
{{output}}
An Er:Yb:YAB crystal laser emitting at 1.55 µm, optically pumped by a vertical external cavity surface emitting 980-nm laser (OP-VECSEL), is reported in this study. To the best of our knowledge, this is the first demonstration of an Er:Yb:YAB laser pumped by ... ...
