FIG. 1.

(Color online) Experimental setup for the OPG in PPKTP. The pump pulse of wavelength is polarized along the axis of the crystal. Inside the crystal, a -polarized signal and a -polarized idler (in the crystal coordinates) are created through spontaneous parametric downconversion and amplified via parametric amplification. The group velocity condition ensures that the signal and idler propagate in the opposite directions in the reference frame of the pump pulse, creating a feedback condition for optical parametric oscillation.

(Color online) Optical spectra of the output from the OPG at pump energy of . (a) The cross-polarized downconversion components of signal and idler pulses. The two components are roughly centered at , albeit separated from each other by approximately , with a FWHM bandwidth of . (b) The parasitic SFG component, which centers at with a FWHM bandwidth of .

(Color online) Internal conversion efficiencies of the downconversion components and the parasitic components. The system has a pump energy threshold of for oscillation. At pump energy of , the total conversion efficiency reaches the maximum of 43%, with the efficiencies of signal and idler being 26% and 17%, respectively.
