Waveguide lasers in (Yb,Nb):RbTiOPO4
Waveguide lasers in (Yb,Nb):RbTiOPO4
In this paper we present lasing results with a planar (Yb,Nb):RbTiOPO4 waveguide device. We also demonstrate channel waveguiding in an ion-beam etched (Yb,Nb):RbTiOPO4 thin film for the first time with a loss of 2.4 dB/cm. To reduce the losses, a study of reactive ion etching of RbTiOPO4 was carried out resulting in structures with a surface roughness of 6.6nm and an etch rate of 13nm/minute.

Abstract
In this paper we present lasing results with a planar (Yb,Nb):RbTiOPO4 waveguide device. We also demonstrate channel waveguiding in an ion-beam etched (Yb,Nb):RbTiOPO4 thin film for the first time with a loss of 2.4 dB/cm. To reduce the losses, a study of reactive ion etching of RbTiOPO4 was carried out resulting in structures with a surface roughness of 6.6nm and an etch rate of 13nm/minute.
