OPTICAL PARAMETRIC LASER AMPLIFIER PREPARATION METHOD AND OPTICAL PARAMETRIC LASER AMPLIFIER

WIPO Patent Application WO/2019/148353

A1

Disclosed are an optical parametric laser amplifier preparation method and an optical parametric laser amplifier, comprising: determining a mapping relationship between a first non-collinear angle and a second non-collinear angle by using a preset non-collinear phase matching formula, wherein the first non-collinear angle is the angle between the transmission directions of a pump beam and a signal beam, and the second non-collinear angle is the angle between the transmission directions of the pump beam and an idler beam; determining a first target non-collinear angle and a second target non-collinear angle based on a preset temperature partial derivative formula and the mapping relationship; and preparing an optical parametric laser amplifier based on the first target non-collinear angle and the second target non-collinear angle. The performance of the optical parametric laser amplifier prepared by the above method is not greatly affected by temperature variation. When the temperature of the non-linear crystal changes and deviates from the original phase matching temperature, the second target non-collinear angle is automatically adjusted to perform phase compensation, such that the phase matching of the optical parametric laser amplifier is not lost, thereby improving the energy conversion efficiency of an optical parametric laser amplifier operating with a high mean power.
