摘要: Continuous-wave single-frequency tunable 544- and 272-nm beams have been demonstrated by the second- fourth-harmonic conversions of a 1088-nm fundamental beam from diode-oscillator fiber-amplifier. The single-pass second-harmonic generation with MgO-doped periodically poled stoichiometric LiTaO3 crystal external-cavity frequency-doubling technique bulk BBO were employed to achieve an approximately 6-W 544-nm 1.5-W beam, respectively. We characterized generations discussed their applications calcium spectroscopy.
