NONLINEAR OPTICAL SYSTEM FOR GENERATING HIGH AVERAGE POWER TUNABLE LIGHT

原文（中国語）

An image rotating optical parametric oscillator, comprising: optical elements that are (i) located and oriented to form a non-planar, image-rotating ring cavity and (ii) configured to rotate a resonating beam by a defined number of degrees for each round trip in the cavity; and non-linear optical crystal(s) configured to convert energy of a pump beam of light into an idler beam of light having a first color and a signal beam of light having a different second color; wherein the non-linear optical crystal(s) is (are) cut such that the idler beam of light propagates in a first direction that is different than a second direction in which the signal beam of light propagates through the at least one non-linear optical crystal; and wherein a power of the signal beam of light exiting the image rotating optical parametric oscillator is three to six magnitudes larger than a power of the signal or idler wave seed.
