Mtg. Canva et al., QUADRATIC SPATIAL SOLITON GENERATION BY SEEDED DOWNCONVERSION OF A STRONG HARMONIC PUMP BEAM, Optics letters, 22(22), 1997, pp. 1683-1685
Two-dimensional quadratic spatial solitons were generated experimental
ly near phase-matching conditions for type II frequency doubling in KT
P by the seeding of a strong second-harmonic field with a weak input a
t the fundamental wavelength. The self-trapped beams were shown to be
insensitive to the energy, phase, and polarization of the fundamental-
frequency seed input beam. (C) 1997 Optical Society of America.
