Abstract
High pump pulse energies and large beam waists are highly advantageous in operation of optical parametric oscillators (OPOs) based on highly birefringent nonlinear materials such as β-bariuin borate (BBO). Reduced beam overlap due to extraordinary wave walk-off can be made less significant through the use of large beam dimension in the walk-off plane.1 The large beam waists involved in our work, using a 150-mJ XeCl excimer laser to pump such an OPO, have enabled us to observe several distinct noncollinearly phase-matched processes in which maximized beam overlap is vital.
