Field, S.J., Hanna, D.C., Large, A.C., Shepherd, D.P., Tropper, A.C., Chandler, P.J., Townsend, P.D. and Zhang, L. (1991) Low threshold ion-implanted Nd:YAG channel waveguide laser Electronics Letters, 27, (25), pp. 2375-2376. (doi:10.1049/el:19911470).

Record type: Article


The first channel waveguide laser in Nd:YAG showing a threshold reduction of 20 times compared to a planar waveguide is described. With diode pumping this ion-implanted waveguide laser has been operated with absorbed power thresholds as low as ~500µW in good agreement with theoretical expectation. Output slope efficiencies of ~29% have also been demonstrated.
