5-GHz mode locking of a Nd:YLF laser.
A frequency-modulated Nd:YLF laser has been mode locked at a repetition rate of 5.4 GHz by using 20 mW of microwave power applied to a LiTaO(3) electro-optic phase modulator in a short (2-cm) laser cavity. The 13-ps pulse duration is shorter than expected on the basis of mode-locking theory for homogeneously broadened transitions and is attributed to inhomogeneity associated with spatial hole burning.
