WebMar 2, 2024 · RTPO is based on nonlinear frequency conversion exploiting nonlinear optical properties of certain materials. In RTPO, a process analogous of optical parametric down-conversion is exploited to get the THz output. 2 Experimental Results: A pump laser of 1064 nm wavelength has been used as source. Optical parametric generation (OPG) (also called "optical parametric fluorescence", or "spontaneous parametric down conversion") often precedes optical parametric amplification. In optical parametric generation, the input is one light beam of frequency ωp, and the output is two light beams of lower frequencies ωs and ωi, with the requirement ωp=ωs+ωi. These two lower-frequency beams are called the "signal" and "idler", respectively. greenland halibut ifmp
