Abstract
The results of experimental study on a complex cavity Nd:YAG laser pumped LiNbO3 crystal optical parametric oscillator(OPO) is reported.Average output pulse energies of 56.4mJ of the OPO and 22.8mJ of the idler at 3097nm were observed with the pulse width of 8ns.The conversion efficiency from 1060nm pumping laser to the OPO output (the signal and idler) was 46% at pulse repetition rates up to 10Hz.The tuning ranges of the OPO obtained by angle tuning the LiNbO3 crystal were 1479nm～1621nm of the signal,and 3097nm～3793nm of the idler.
