OPTICAL PARAMETRIC OSCILLATOR FOR GENERATING TERAHERTZ RADIATION

摘要

An optical parameter oscillator (OPO) is pumped at pump wavelength λ_P to resonate at signal wavelength λ_S. The OPO produces idler radiation at terahertz frequencies ν_THz=c/λ_P−c/λ_S. The pump, signal, and idler radiation are substantially collinear.
