General analysis of type I second-harmonic generation with elliptical Gaussian beams
The optimal focusing arrangement for second-harmonic generation is a compromise between the focal intensity and the depth of focus (confocal parameter) within the crystal. In the absence of birefringence (noncritical phasematching), the fundamental beam should have a circular cross section and a confocal parameter of 0.35 of the crystal’s length.1 Angle-tuned (critical) phase matching causes th...
متن کاملC W second harmonic generation with elliptical Gaussian beams
We present a study of the efficiency and optimization of cw second harmonic generation by elliptical Gaussian laser beams. Elliptical focusing slightly improves conversion efficiency and reduces crystal damage risk when heavy walk-off is present. Single-pass measurements of the efficiency for doubling 5 15-nm radiation in beta-barium borate (BBO) agree with theory. Thermal effects, caused by ra...
متن کاملSecond- and third-harmonic generation with vector Gaussian beams
We consider second-harmonic generation (SHG) and third-harmonic generation (THG) in a nonlinear optical crystal illuminated by a vector Gaussian beam, i.e., a Gaussian beam in which the axial component of the excitation field is considered. This component exhibits twice the Gouy phase shift of the transverse component and vanishes at points on the beam axis. Harmonic generation stemming from th...
متن کاملType I and type II second harmonic generation of conically refracted beams.
Type I and type II second harmonic generation (SHG) of a beam transformed by the conical refraction phenomenon are presented. We show that, for type I, the second harmonic intensity pattern is a light ring with a point of null intensity while, for type II, the light ring possesses two dark regions. Taking into account the different two-photon processes involved in SHG, we have derived analytica...
متن کاملGeneration of second-harmonic beams with switchable curved trajectories
Beamswhich follow curved trajectories are useful in a variety of applications, but up to now have been realized mainly in linear media. We demonstrate theoretically and experimentally the generation of second-harmonic (SH) beams which follow arbitrary convex caustic trajectories. These beams are created in a nonlinear photonic crystal with a second-order susceptibility having a tailored pattern...
