Abstract

The invention relates to a laser frequency conversion device, particularly to a built-in high flux and large diameter laser frequency conversion device which aims at achieving high flux and large diameter laser frequency conversion. A frequency conversion module mechanism is arranged inside a frequency conversion module housing; an optical element dismounting flange window is formed on a lateral wall of a mechanism case; a frequency-doubled first micro-driving mechanism and a first frequency-mixed first micro-driving mechanism are both arranged inside another lateral wall of the mechanism case; the first frequency-mixed first micro-driving mechanism is located on the upper portion of the frequency-doubled first micro-driving mechanism; a second frequency-mixed first micro-driving mechanism is arranged at the bottom end of the inner wall of the mechanism case; the bottom end of the inner wall of the mechanism case, which is arranged on one side of the optical element dismounting flange window, is close to the second frequency-mixed first micro-driving mechanism; and a frequency-doubled angle modulation assembly, a first frequency-mixed angle modulation assembly and a second frequency-mixed angle modulation and movement assembly are sequentially arranged inside the mechanism case in a parallel mode. The built-in high flux and large diameter laser frequency conversion device is used for the high flux and large diameter laser frequency conversion.

Description

technical field [0001] The invention relates to a high-flux, large-diameter and high-precision optical element frequency conversion device, in particular to a built-in high-throughput large-diameter laser frequency conversion device. Background technique [0002] The high-throughput large-aperture laser frequency conversion device is an important part of the vacuum controllable high-throughput large-aperture optical focusing and frequency conversion system. Its main function is to convert the fundamental frequency light with a wavelength of 1.053 μm into a triple frequency of 0.351 μm Light. And it adopts "Class I + Class II / Class II" crystal cascading method to realize high efficiency, high strength, high stability and broadband third harmonic conversion. At present, there is no mature device to realize high-throughput large-aperture laser frequency conversion device. Contents of the invention [0003] The object of the present invention is to realize frequency conversi...
