Title:
WAVELENGTH CONVERSION SYSTEM, SOLID LASER SYSTEM, AND ELECTRONIC DEVICE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/089777
Kind Code:
A1
Abstract:
A wavelength conversion system according to one aspect of the present disclosure comprises: a first non-linear optical crystal (51) on which first light (B1) having a first wavelength is incident, and which outputs second light (B2) having a second wavelength that is a second harmonic of the first light; a second non-linear optical crystal (52) on which the second light (B2) and third light (B3) having a third wavelength are incident, and which outputs the third light (B3) and fourth light (B4) having a fourth wavelength that is the sum frequency light of the second light and the third light; a third non-linear optical crystal (53) on which the third light (B3) and the fourth light (B4) are incident, and which outputs fifth light (B5) having a fifth wavelength that is the sum frequency light of the third light and the fourth light; a light condensing optical system (55a) which causes the first light (B1) to be incident on the first non-linear optical crystal (51) such that the beam waist position of the second light (B2) is disposed inside the second non-linear optical crystal (52). The first non-linear optical crystal (51) is disposed in a range within the Rayleigh length (zR2) of the second light from the beam waist position (P2) of the second light, and the third non-linear optical system (53) is disposed in a range within the Rayleigh length (zR4) of the fourth light from the beam waist position (P2) of the second light.
