Abstract
Knowing the correlation between the Nd3+ excited-state Lifetime in pro ton-exchanged waveguides and the phase diagram of the HxLi1-xTaO3 comp ound permits optimized waveguide fabrication parameters to be found. T hese have been used to produce a Nd:LiTaO3 waveguide laser with a thre shold of 2.9 mW and a slope efficiency of 33%, in good agreement with the best predicted values. Nevertheless this component suffers from in stabilities because of the photorefractive effect.
