摘要： A light processing apparatus includes a first non-linear crystal disk for transmitting a first beam of photons having a first frequency to a second beam of photons having the first frequency and a second frequency oscillating in polarization directions orthogonal to each other, the second frequency being a half of the first frequency. Further included is a waveplate for transmitting the second beam of photons to a third beam of photons by rotating polarization directions of the second beam of photons such that the photons of the first frequency and of the second frequency oscillate in the same polarization directions. A second non-linear crystal disk is configured to transmit the third beam of photons to a fourth beam of photons of the first frequency, the second frequency and a third frequency, the third frequency being approximate a third of the first frequency.
