Pt. Nee et Nc. Wong, OPTICAL FREQUENCY-DIVISION BY 3 OF 532 NM IN PERIODICALLY POLED LITHIUM-NIOBATE WITH A DOUBLE GRATING, Optics letters, 23(1), 1998, pp. 46-48
Optical frequency division by 3 of 532 nm is demonstrated by back-to-b
ack difference-frequency generation in a periodically poled lithium ni
obate crystal with a double grating. The first grating generates 1596-
nm light from 532- and 798-nm inputs, and the second grating mixes the
798-nm input and the 1596-nm output from the first grating to produce
a second 1596-nm output. The beat signal between the two 1596-nm outp
uts is detected and frequency stabilized to yield the 3:1 frequency ra
tio. (C) 1998 Optical Society of America.
