Received 18 June 2008; accepted 18 September 2008

The diffraction of idler beam generated in optical parametric amplifier operating at low parametric gain is analysed. It is revealed that diffraction properties of idler beam under propagation in the free space is significantly different in comparison with the properties of Gaussian beam.
Keywords: nonlinear optics, diffraction, optical parametric amplifier

Išanalizuota anomali šalutinės bangos, generuojamos optiniame parametriniame stiprintuve, difrakcija mažo stiprinimo atveju. Parodyta, kad šalutinės bangos, sklindančios laisvoje erdvėje, difrakcinės savybės esmingai skiriasi nuo Gauso pluoštui būdingų savybių
