SHG conversion efficiencies of 50% were typically achieved with a 10.3 mm long crystal and a fundamental peak-power density of 32 MW/cm(2). It was found that any optical index inhomogeneities were not induced for more than 2 h operation of SHG under the fundamental power density of 32 MW/cm(2). (C) 1997 Elsevier Science B.V.
