Title:
MINIATURE MID-INFRARED LASER BASED ON DOUBLE MICRODISKS
Document Type and Number:
WIPO Patent Application WO/2022/077997
Kind Code:
A1
Abstract:
A miniature mid-infrared laser based on double microdisks, comprising a laser source (1), a coupler (2), an echo wall microdisk laser (3), and an echo wall microdisk optical parametric oscillator (4). The echo wall microdisk laser (3) and the echo wall microdisk optical parametric oscillator (4) are stacked; the coupler (2) comprises a first lens (21), a lower coupling crystal (22), an upper coupling crystal (23), and a second lens (24); the lower coupling crystal (22) and the upper coupling crystal (23) are stacked; and in an actual application process, the echo wall microdisk laser (3) and the echo wall microdisk optical parametric oscillator (4) are designed to be a stacked double-microdisk structure, and one coupler (2) is used to achieve multiple times of coupling of laser, so that the mass and the size of the miniature mid-infrared laser based on double microdisks are greatly reduced, thus high requirements of the laser on weight and size are met.
