Abstract
In the present work the gain saturation effects in type-I BBO optical parametric amplifier (OPA) pumped by the 3rd harmonic of multi-mode Nd:YAG laser are investigated. The OPA gain was measured as a function of input idler energy at 1064 nm with a constant pump energy at 355 nm and a beam divergence 0,3 mrad. In the 9 mm BBO crystal at pump intensity approximately 68 MW.cm2 and input idler intensity approximately 18 MW.cm2 the efficiency of energy extraction in the saturated gain regime approximately 31% was obtained. The ways to increase the efficiency of energy extraction in the two-crystal OPA configuration are discussed.
