Gigabit optical pulse generation with FM mode-locked LiNdP4O12lasers

FM mode locking of an LiNdP
4
O
12
(LNP) laser with an intracavity modulator is reported. Mode-locked optical pulses with a pulse width of 49 ps at a repetition rate of 960 MHz, corresponding to
c/2L
(
c
:light velocity,
L
:cavity length), have been obtained. A pulse repetition rate as high as 2.88 GHz has been achieved with a multiple mode-locking technique.
