D. Jaque et al., Continuous-wave laser properties of F-4(3/2) -> I-4(13/2) channel in the Nd3+LiNbO3 : ZnO non-linear crystal, APP PHYS B, 70(1), 2000, pp. 11-14
This work reports for the first time continuous-wave laser action at room t
emperature around 1.3 mu m in Nd3+ doped LiNbO3;ZnO. Optical spectroscopy h
as been used to determine the main laser characteristics of F-4(3/2) --> I-
4(13/2) channel, such as emission cross section and excited-state absorptio
n cross section at laser wavelengths. Internal optical losses have been est
imated from laser gain experiments. Under non-optimal conditions laser slop
e efficiencies of 30% have been obtained.
