We all know that fiber laser module has always been used as one of the powerful devices in medicine, and it is used in many departments. Today, Xiaobian focuses on the application of fiber laser module in medical detection.

This topic is actually quite interesting. The application of fiber laser module in medical treatment has been increasing in recent years. When many people listen to "fiber laser", it is easy to think of those scenes of industrial cutting and welding. In fact, it also plays a significant role in medical testing and detection.

Why use fiber laser module? The main reason is that its beam quality is particularly good, its transmission is stable, and it can guide the laser to the front end of a very small probe through optical fiber. This is very convenient for medical instruments. For example, when doing endoscopic examination, tissue scanning and even some precise skin examination, doctors simply don't want the whole set of equipment to be too big and stupid, and the fiber laser module can just achieve small volume and high precision output.

Now some hospitals will use spectral imaging technology when doing early detection of cancer cells. In this system, a small fiber laser module is often embedded, and the light emitted by it passes through the tissue and then passes through the spectrum analyzer to read the reflected signal. Through the reflection difference at different wavelengths, we can judge whether there is abnormality in the tissue. This detection method is faster and safer than traditional slicing.

In addition, the role of fiber laser module is also quite obvious in surgical positioning and biosensing. For example, some precision surgical robots will use laser modules to assist in positioning. Because the fiber laser has good stability and small divergence angle, it can accurately irradiate the target site during the operation. In a device we debugged before, the laser power was required to be stable at 0.5%, which is almost difficult to achieve without fiber laser module.

Generally speaking, this technology will be more and more widely used in blood testing, tissue identification and intraoperative navigation in the future.

Nowadays, many medical instrument manufacturers no longer rely solely on LEDs or ordinary laser tubes, but prefer to choose integrated and controllable fiber laser modules.
