A semiconductor laser die detection device

Abstract

The invention belongs to the technical field of optical communication, and especially relates to a semiconductor laser tube core detection device. The device includes a case body; the upper surface ofthe base plate of the case body is slidingly connected to a slide plate; the slide plate is fixed through a clamping mechanism; the sidewall of the slide plate is fixedly connected to a push plate; the upper surface of the slide plate is slidingly connected to two compression plates; the compression plates are tightly locked through a locking mechanism; the upper side of the slide plate is provided with a calibrated scale; the calibrated scale is fixedly connected to the sidewall of the case body; one side of the calibrated scale is provided with a baffle plate; the baffle plate is fixedly connected to the inner sidewall of the case body through a fixing mechanism; the lower surface of the top plate of the case body is fixedly connected to multiple second springs; and the lower ends of the second springs are fixedly connected to a movable plate. The advantages of the device are as follows: the length values and straightness of semiconductor laser tube cores after production can be conveniently detected, so that the detection efficiency of the semiconductor laser tube cores can be enhanced through the device.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a semiconductor laser tube core detection device. Background technique [0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working substances. Semiconductor diode lasers are the most practical and important type of lasers. They are small in size, long in life, and can be pumped by simple injection current. The working voltage and current are compatible with the integrated circuit, so it can be monolithically integrated with it. The semiconductor laser is a device that produces stimulated emission by using a certain semiconductor material as the working substance. Between the energy band of the semiconductor material (conduction band and valence band), or between the energy band of the semiconductor material and the energy level of the impurity (acceptor or donor), the particle population inversion of ...

Problems solved by technology

[0003] However, the existing semiconductor laser die detection device generally cannot detect the length value and straightness of the semiconductor laser die at the same time, so it takes more time for the staff to detect the semiconductor laser die after production, which improves the quality of the enterprise. production cost
