Observations of spontaneous phase locking of LiNdP4O12lasers

Spontaneous or self-locking effects of the TEM
00
mode at 1.05 μm have been observed for an LiNdP
4
O
12
(LNP) laser. Pulse repetition frequency was 600 MHz, corresponding to
c/2L
(
c
: light velocity,
L
: cavity length). The effect of low-frequency resonance on self-locking is also discussed experimentally.
