Title:
SERVO MATCHING CONTROL MID-INFRARED DIFFERENTIAL DUAL-WAVELENGTH LASER BASED ON MULTI-PERIOD ND:MGO:PPLN
Document Type and Number:
WIPO Patent Application WO/2022/166102
Kind Code:
A1
Abstract:
Disclosed is a servo matching control mid-infrared differential dual-wavelength laser based on Nd:MgO:PPLN, comprising: an 813-nm pump source, an energy-transferring optical fiber, a first focusing mirror, a second focusing mirror, a first 45-degree beam splitter, a mid-infrared idle frequency light output mirror, a multi-period Nd:MgO:PPLN polarized crystal, a servo motor, a mid-infrared idle frequency light total reflection mirror, a single chip microcomputer, a second 45-degree beam splitter, an electro-optical crystal, a 1093-nm fundamental frequency light total reflection mirror, and a 1084-nm fundamental frequency light total reflection mirror, wherein: the 813-nm pump source, the energy-transferring optical fiber, the first focusing mirror, the second focusing mirror, the first 45-degree beam splitter, the mid-infrared idle frequency light output mirror, the polarized crystal, the servo motor, the mid-infrared parametric light total reflection mirror, the single chip microcomputer, the second 45-degree beam splitter, the electro-optical crystal and the 1093-nm fundamental frequency light total reflection mirror are sequentially placed from right to left in a straight cavity of the laser; and the 1084-nm fundamental frequency light total reflection mirror is placed in a bent-shape cavity and corresponds to the position of the second 45-degree beam splitter, such that the second 45-degree beam splitter can reflect incident light to the 1084-nm fundamental frequency light total reflection mirror.
