Parametric Amplification in Spatially Extended Media and Application to the Design of Tuneable Oscillators at Optical Frequencies

摘要: A theory of traveling wave and backward variable-parameter amplification appropriate to the a light beam is developed. It an extension Tien Suhl for one-dimensional propagation case in which pump wave, signal idler waves have different directions propagation. The then applied design tuneable oscillator at optical wavelengths. device tuned by changing orientation parallel mirror system. appears that currently available pulsed laser powers are sufficient drive such devices continuous tuning range over three-to-one interval frequency possible.
