We all know that there are many packaging forms of laser diodes, so do you know the specific ones? Let's take a look at it together. In addition, many people are asking what advantages laser diodes have, and I will give you an answer today.
There are several common packaging forms.
The more traditional one is TO tube package, which has the advantages of simple structure, relatively low cost and good heat dissipation performance. It can be seen in many scientific research equipment and low-power applications.
Going further up, it is a Butterfly package. The name is quite vivid and there are pins on both sides. Its biggest advantage is that it can directly couple optical fibers, and its stability is high, which is suitable for demanding optical communication and industrial laser scenes.
There is also an open package such as C-Mount and F-Mount, which looks simple. The chip is directly fixed on the metal base, and the heat dissipation is very fast, which is common in high-power applications.
In addition, micro-packaging and modular packaging are becoming more and more common, especially in portable devices, which are small in size and flexible in assembly, which is convenient for manufacturers to integrate according to different needs.
After packaging, talk about its advantages.
The efficiency of laser diode is very high. When electricity is added, it can be quickly converted into light with high intensity, good directivity and small divergence angle, which means that the beam is easy to focus and can achieve high energy density in a small range. Such as cutting and welding, efficiency is the core competitiveness.
Compared with the bulky gas laser, the laser diode module is small, but it can work stably for thousands or even tens of thousands of hours. For enterprises, this means less equipment downtime and low maintenance costs.
The spectrum of laser diode is wide, covering from visible light to infrared band. Like our common red light positioning module, optical fiber communication equipment, and even semiconductor laser instruments for medical beauty, almost all of them rely on its output ability in different bands.
I remember visiting a metal welding factory once, and the boss mentioned that they used traditional welding, which was slow, consumed a lot of materials and the weld was not fine enough. After the welding module based on laser diode is replaced, not only the efficiency is doubled, but also the appearance of the workpiece is improved a lot. The boss said with a smile that it used to be polished after welding, but now it is basically unnecessary to start work, and the customer inspection is smoother. This case actually illustrates a simple truth: in the final analysis, the value of technology is still reflected in "saving trouble, saving money and worrying".
Therefore, the laser diode can be regarded as the most practical and potential device in the modern optoelectronic industry, no matter from the diversity of packaging forms or from the performance advantages.
