A ground state depleted (GSD) laser has been demonstrated at 912 nm in the form of a Q-switched oscillator operating on the Nd{sup 3+}{sup 4}F{sub 3/2}-{sup 4}I{sub 9/2} transition in Y{sub 2}SiO{sub 5}. Samarium scandium gallium garnet has been demonstrated effective at selectively suppressing the competing and much stronger {sup 4}F{sub 3/2}-{sup 4}I{sub 11/2} lasing transition. Efficient harmonic generation has been demonstrated using non-critically phase matched KNbO{sub 3}. 15 refs., 15 figs., 3 tabs.
