Kh. Al'brekht, A. I. Kovrigin, P. V. Nikles


Abstract: An experimental investigation was made of the frequency stability of parametric light sources. It was found that the stability of the output frequency of KH₂PO₄ and α-HIO₃ parametric light sources was two to three times higher than the stability of the pump frequency. The results obtained were compared with theoretical calculations.
