Here we present the design and fabrication of a chirped periodically poled lithium niobate (CPPLN) nonlinear photonic crystal that supports multiple orders of quasiphase matching with finite bandwidth and allows for the simultaneous broadband generation of second and third harmonics with high conversion ...
χ(3)s, of tungsten diselenide (WSe2). With a home-built multiphoton microscope setup developed to study harmonics generation, we map the second and third-harmonic intensities as a function of position in the sample, pump power and polarization angle, for single- and few-layers flakes...

We report generation of the second, third, fourth, and fifth harmonics of the output of a Yb-doped fiber amplifier seeded by a passively Q-switched Nd:YAG microchip laser. We obtained high conversion efficiencies using a simple optical arrangement and critically phase-matched nonlinear crystals. ...
By means of second harmonic generation (SHG), third harmonic generation (THG) and fourth harmonic generation (FHG), not only the wavelength range but also the versatility of laser sources can be vastly extended. The UHG series offers widely tunable harmonic generation in a compact, modular ...
The class A/F amplifier substantially reduces harmonics in the radio frequency signal that cause power interference between adjacent channels, resulting in greatly improved mobile communication service having much fewer dropped calls and an enhanced calling range....
Such effects have been extensively studied since 80-th, in semiconductors as well as in other materials at optical frequencies for second and third harmonics generation, sum-frequency generation and optical Kerr effect. Both bound and free electrons may give contribution to \({\chi }^{(3)}\)...
