T. Hatanaka et al., Dual signal-wave optical parametric oscillator using periodically poled LiNbO3 with series gratings, ELECTR LETT, 36(16), 2000, pp. 1409-1411
The authors present a dual signal-wave quasi-phase-matched optical parametr
ic oscillator using periodically poled LiNbO3 with two grating periods. The
wavelength separation of the signal waves was tuned from 2 to 22 nm by cha
nging the grating periods and temperature in the 1.3-1.5 mu m wavelength ra
nge.
