Paper Abstract

The performance of collinear and noncollinear pulsed barium borate optical parametric oscillators is analyzed under third harmonic Nd:YAG pumping. In the collinear case the effects of output coupling, cavity length and pump spotsize on threshold and slope efficiency have been measured and compared to a simple model. Tuning ranges, bandwidths and efficiencies are compared for collinear operation and for both directions of noncollinear operation. For a low pump divergence collinear operation is more efficient, but noncollinear operation is favored for a pump divergence in excess of 4 milliradians. Single frequency OPO operation with less than 250 MHz bandwidth is obtained using a simple new injection seeding technique for both signal and idler. Precise crystal temperature control is used to simultaneously manipulate the gain envelope and mode frequencies, ensuring stable seeding on the strongest mode.
