Spectra for (a) 1550 nm pump, (b) SHG at λcentral = 773 nm and (c) THG at λcentral = 516 nm. The pump beam full-width at half-maximum (FWHM) bandwidth is 25.1 nm, but only the peak centered at 1546 nm contributes for the harmonic generation (dotted line, FWHM bandwidth ~ 16.3 nm). The FWHM bandwidth and central wavelength for SHG are 8.1 nm and 773 nm, and for THG are 5.8 nm and 516 nm, respectively.
