Self-suppression of axial-mode-hopping via intracavity second-harmonic generation

Martin, K.I., Clarkson, W.A. and Hanna, D.C. (1997) Self-suppression of axial-mode-hopping via intracavity second-harmonic generation Optics Letters, 22, (6), pp. 375-377. (doi:10.1364/OL.22.000375).

Record type: Article


Intracavity second-harmonic generation (SHG) in a single-frequency laser has an associated loss for adjacent nonlasing modes, from sum-frequency generation, that is greater than the loss from SHG for the lasing mode. Mode hopping is thereby suppressed, as the lasing mode dominates neighboring modes. We have investigated this behavior in a Nd:YAG laser with LBO intracavity frequency doubler, obtaining frequency tuning over more than 80 axial mode spacings, without mode hopping.
