Abstract:

The problem of second harmonic generation in uniaxial crystals at angles of synchronism close to 90° is considered at an assumed field approximation. It is shown that this important special case is characterized by a number of distinctive features, which were not discussed earlier and, what is more important, contradict to the common ideas of the physics of the considered process.

Keywords:

second harmonic generation, uniaxial crystal, 90°-synchronism, optimal wave length, optimal focusing
