A low threshold epitaxially grown Nd:YAG waveguide laser operating at 946nm
The 946-mn transition of Nd:YAG has attracted interest asa possible source of diode- pumped blue light (after frequency doubling). A problem with this transition, however, is its three-level nature, with 0.7% of the total Nd population residing in the lower laser level at room temperature. Moving to a waveguide geometry gives the advantage of better light confinement, which should lead to significantly lower thresholds even despite some added propagation loss introduced by the guide.

Abstract
The 946-mn transition of Nd:YAG has attracted interest asa possible source of diode- pumped blue light (after frequency doubling). A problem with this transition, however, is its three-level nature, with 0.7% of the total Nd population residing in the lower laser level at room temperature. Moving to a waveguide geometry gives the advantage of better light confinement, which should lead to significantly lower thresholds even despite some added propagation loss introduced by the guide.
