Abstract

The invention provides a multi-segment temperature soldering packaging device and method for a miniature solid laser. The device comprises a base plate, a ceramic heating sheet and fixing parts; the fixing parts comprise optical elements and supports, and each optical element is fixed to the corresponding support; the ceramic heating sheet is closely attached to the lower surface of the base plate; the base plate is fixed to an operating platform which has the cooling function and is resistant to high temperature, the base plate is provided with one or more grooves, each groove is filled with soldering materials different in fusion point, and each support to which the corresponding optical element is fixed is fixed into the corresponding groove through the corresponding soldering materials; a thermistor is installed on the side wall of the base plate. The soldering materials adopted in all the grooves are different in temperature, when each fixing part is soldered, the previous fixing part which is soldered ready is not influenced, the fixing parts and the base plate are integrated permanently, and the structure is stable and firm.

Description

technical field [0001] The invention relates to the field of optical assembly and packaging, in particular to a packaging device and packaging method for multi-stage temperature welding of a miniature solid-state laser. Background technique [0002] Laser technology has penetrated into various fields, such as industrial processing, medical equipment, military weapons, biological detection, scientific research and so on. With the development of science and technology, laser technology has gradually entered our lives. Laser display, the pursuit of bright super-large picture, pure color, and high-resolution display effect, has always been a potential requirement for people's visual experience. From the establishment of command and monitoring centers and network management centers to the conduct of video conferencing, academic reports, technical lectures and multi-functional meetings, the desire for large screen, multi-color, high-brightness, and high-resolution display effects...
