Paper Abstract

The linewidth of KBe2BO3F2 crystal optical parametric oscillator (KBBF-OPO) has investigated using theoretical analysis and simulation in type-I phase matching (PM). The Linwidth ranges of 81~250nm with the spontaneous parametric emission, 230~690nm with the divergence angle of pumping beam, and 19~96nm the linewidth of signal light are obtained, respectively. It is shown that the linewidth of signal is very narrow far away from the degeneracy point and the linewidth increased near the degeneracy point and given the results that KBBF-OPO has smaller linewidths than that of CLBO-OPO in type I. The divergence angle of pumping beam and the off-axis of pumping beam influenced the signal linewidth more seriously than other factors do. These results are important for compression the linewidth of OPO signal and useful for construction high power KBBF-OPO laser.
