Observation of Self-Frequency Doubling in Diode-Pumped Mode-Locked Nd-Doped La₃Ga₅SiO₁₄ Laser

【摘要】 A diode-pumped passively mode-locked Nd-doped La₃Ga₅SiO₁₄（Nd:LGS） laser is realized by using a semiconductor saturable absorber mirror.With the pump power of 2W,we obtain a 532 nm self-frequency doubling（SFD） laser together with a 10.9ps fundamental laser at the repetition rate of 173.7MHz.To the best of our knowledge,it is the first time for self-frequency doubling in the diode-pumped mode-locked Nd:LGS laser.Benefited from the diode lasers and its self-frequency doubling property,Nd:LGS could be a potential candidate for compact,stable and cheap ultrafast green laser sources.更多还原
