WebAug 4, 2024 · However, the conversion efficiency will consequently decrease dramatically because it is quadratically proportional to the crystal length. Other methods have been proposed to use aperiodically poled PPLN [8, 9] or chirped PPLN . However, despite a theoretically estimated large bandwidth of 1045.9 nm centered at 3.5 μm, the effective … Webmatched the polarization of the chirped-and-delayed pulses to the optical axis of the PPLN. Two cylindrical telescopes matched the beam shape to the clear aperture of the PPLN: the tangential and sagittal telescopes reduce the vertical and horizontal beam size to 3mm and 10mm, respectively to match the aperture of the PPLN.
WebMar 25, 2010 · We experimentally demonstrate a 160-Gb/s tunable and phase-transparent wavelength conversion using cSFG-DFG in a linear-chirped PPLN. Thanks to the … WebMar 29, 2024 · The nonlinear processes including sum-frequency generation, difference-frequency generation and second harmonic generation are discussed in both periodic poled lithium niobate (PPLN) and chirped PPLN (CPPLN) structures.
WebThe design and fabrication of the chirped PPLN is easier than that of APLN, and more impor-tantly, the chirped PPLN retains the characteristics of both high gain coefficient and broad bandwidth. Theoretical analysis shows that the chirped PPLN may exhibit a serious ripple phenomenon in its spectral output[11], which is not conducive to the ... WebInthe experiment, we use a z-cut PPLN thin plate sample with dimensions of 5mm x ×20 mm y × 1mm z and a z-cut CPPLN thin plate sample with dimensions of 6mm x × 20 mm y × 0.5mm z as the nonlinear media. The poling period of the PPLN sample is fixed at a value of 6.96 μm and that of CPPLN ranges from 24 to 14.8 μm with a mean value of 18. ...
