Abstract Second harmonic generation conversion efficiencies of Nd:YCOB and Nd:GdCOB were measured, the effective nonlinear coefficient (deff) for both crystals at different phase-matching angles were estimated by comparison with a KTP crystal. The self-frequency doubling laser performance of these crystals were theoretically calculated by using these deff values and slope efficiency of the fundamental wave and lasing threshold. The results coincide very well.
