Title

Bandwidth enhancement of second-harmonic generation with quadratic spatial-soliton generation versus conventional methods

Abstract

A detailed numerical comparison of the bandwidth-efficiency trade-off for second-harmonic generation (SHG) achieved by the formation of two-dimensional quadratic spatial solitons versus the more conventional method of gentle focusing in the middle of a nonlinear crystal is presented. Numerical simulations for type II SHG in potassium titanyl phosphate with constant wave-vector mismatch show that the 3-dB drop-off in SHG conversion efficiency can be many multiples of π in detuning from the phase-match condition over a large range of walk-off angles and focal positions. © 1998 Optical Society of America [S0740-3224(98)01911-0].
