Fig.#cod#x00A0;3. OPG signal energy versus pump energy at 532#cod#x00A0;nm from the 10.30-#cod#x03BC;m-period PPLN crystal phase-matched at 100#cod#x00A0;#cod#x00B0;C with the 1064#cod#x00A0;nm beam blocked. Inset gives the dependence of SFG energy on the OPG signal energy when the 1064#cod#x00A0;nm beam was added into PPLN.
