Correction to 'Bandwidth and threshold calculations for angle-tuned parametric oscillator'
In the above paper, Basu and Steier have derived an expression [equation (18)] for the threshold of a single resonant optical parametric oscillator in which they take account of the effects of noncolinearity and walk-off of the interacting beams. In deriving (18), an erroneous assumption has been made, viz., that under low gain condition all three waves - pump, signal, and idler - may be taken to be constant over the length of the crystal. While this is a good approximation for the pump wave and the resonated wave (idler in their notation), it is not so for the non-resonant wave since this has zero amplitude at the entrance face to the nonlinear medium and grows to a level comparable to the idler amplitude by the time it reaches the exit face.

Abstract

In the above paper, Basu and Steier have derived an expression [equation (18)] for the threshold of a single resonant optical parametric oscillator in which they take account of the effects of noncolinearity and walk-off of the interacting beams. In deriving (18), an erroneous assumption has been made, viz., that under low gain condition all three waves - pump, signal, and idler - may be taken to be constant over the length of the crystal. While this is a good approximation for the pump wave and the resonated wave (idler in their notation), it is not so for the non-resonant wave since this has zero amplitude at the entrance face to the nonlinear medium and grows to a level comparable to the idler amplitude by the time it reaches the exit face.
