Then the two auxiliary equations, where the restoring force functions are odd, are solved by using a first harmonic term (without a constant).
This part of the work was completed by a second harmonic generation (SHG) study as an alternative method to probe interfacial properties.
The effect of intentionally adding dissolved aluminum on electrokinetic potential of basal plane surfaces of sapphire was studied by streaming potential measurements as a function of pH and was complemented by a second harmonic generation (SHG) study at pH 6.
Excitation light is provided by dye laser emission (DCM 650) in a home built dye cell which is pumped by a second harmonic Minilite Nd YAG laser (Continuum).
In this report, nanosized barium titanium oxide (BaTiO3, BTO) crystals were utilized as probes for mRNA quantification by a second harmonic super-resolution microscopy (SHaSM).
SHG holography is an interferometric technique that records the amplitude and phase of a SHG object field and a more powerful reference field generated by a second harmonic crystal.
First, the frequency of the output of a commercial mode-locked femtosecond Ti:sapphire laser (Mai Tai BB, Spectra Physics, USA) operating at 800 nm was frequency doubled by a second harmonic generation (SHG) crystal (BBO, Castech, China), and then passed through a 650 nm short pass filter (SP650, DHC, China) to remove residual fundamental laser (Fig. 1 ).
We investigated the ferroelectric domains of a tetragonal BiFeO3 film by using a second harmonic generation (SHG) technique.
In addition, the proposed method is able to mitigate the converter circulating current by inserting a second harmonic reference in the modulation process of the MMC, which is the second contribution this paper provides over other control techniques.
Quenching occurs for some cases, where the response due to one resonance can be significantly decreased by application of a second harmonic component associated with another resonance.
