Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below in conjunction with the drawings.

[0026] Such as figure 1 As shown, a fixing fixture for laser life testing can be used for C-Mount packaged single-die semiconductor lasers. It mainly includes a support frame 100, a mounting board 200 arranged on the support frame 100, and a plurality of mounting plates 200 mounted on the mounting board. The metal base 400 is provided with an insulating sheet 800 between every two metal bases 400, the metal base 500 is installed and fixed on the metal base 400, and a connector 600 for connecting the laser 700 on the adjacent base 400 is also installed.

[0027] A laser 700 is installed on the base 500 of each metal base 400, which can achieve the purpose of carrying out the life test on multiple packaged lasers 700 at the same time, and each base 400 is electrically insulated and separated by the insulating sheet 800. The metal base 500 on the base 400 is connected ...

Abstract

The invention discloses a fixing clamp for laser service life testing. The fixing clamp comprises a plurality of metal bases which are arranged side by side, insulating pieces, metal foundation bases and metal connecting pieces. Each insulating piece is arranged between every two adjacent bases. Each metal foundation base is arranged on the corresponding base to be used for fixing a laser. Each metal connecting piece is connected with lasers on two adjacent bases. Non-lead-wire series connection of a plurality of devices is achieved, and large-batch testing on the lasers can be achieved. In addition, the fixing clamp is easy to manufacture and low in cost and has high using value in production.

Description

Technical field [0001] The present invention relates to the technical field of semiconductor lasers, in particular to a fixed fixture for laser life testing. Background technique [0002] Semiconductor lasers are widely used in optical communications, information storage, medical treatment, optical sensing, and pumped solid-state lasers and fiber amplifiers due to their advantages of small size, light weight, high conversion efficiency, and good reliability. Plays a pivotal role. In the above-mentioned application fields, life is an important reliability index to ensure its application. Some important projects have clearly proposed the life assessment requirements for semiconductor lasers for more than 10,000 hours or 109 pulses. [0003] The life assessment of semiconductor lasers requires life evaluation tests, usually two methods: constant current accelerated life test or constant temperature accelerated life test. No matter which life test method is used, multiple devices need...
