MOPA pulse laser cleaning, to meet the surface cleaning needs of various materials

The MOPA fiber laser system's resonant cavity is an optical fiber. MO (Master Oscillator) is a low-power laser; generally, a suitable wavelength laser is selected. The low-power laser LD (laser diode) can directly modulate the output parameters by driving the current, and then couple the signal light generated by the LD into the PA (Power Amplifier) ​​power amplifier system through the pigtail to amplify the signal light. 


MOPA laser is the most widely used laser cleaning. Since the MOPA fiber laser system can strictly amplify according to the seed signal source coupled into the system, it will not change the relevant characteristics of the laser such as the central wavelength, pulse waveform, and pulse width. Therefore, the parameter adjustment dimension is higher and the range is wider. It is more adaptable to different application scenarios of other materials, and the process window range is larger, which can meet the surface cleaning of various materials.

 

In addition, MOPA lasers have a high laser energy margin, and laser cleaning equipment can be upgraded by improving laser cleaning devices, such as increasing the laser processing spot and coordinating intelligent systems. It is worth mentioning that due to the excellent performance and flexible scene applicability of MOPA lasers, they are particularly widely used in emerging industries such as new energy batteries.

History of Lasers

Image
  Lasers have been hailed as one of the great inventions of the twentieth century, following nuclear power, computers, and semiconductors, and have brought about a great technological breakthrough for mankind. The laser radiation produced by lasers is famous for being the "fastest blade", the "most accurate ruler" and the "brightest light". Nowadays, laser technology plays an important role in many fields such as medicine, the military industry, communications, and so on.   The birth of the laser is the result of the tireless efforts and arduous exploration of many scientists.   In 1917, Albert Einstein proposed the concept of "stimulated radiation", which laid the cornerstone for the theoretical foundation of lasers.   Although the theory of lasers had already been proposed at that time, the actual preparation of lasers was quite challenging. By the 1950s, with the progress of photon and microwave technology, the manufacture of an oscillator cap...

Automated laser welding improves MDM yields

Image
Hiring and training skilled personnel is not only costly, but in today's labor market, it is becoming increasingly difficult for companies to find and retain this talent. Automated laser welding systems dramatically reduce the need for skilled personnel. For example, once an engineer or technician has specified and stored all aspects of a welding application using the machine software, the operator can safely initiate the welding process with limited access to functions through the GUI.   Avoiding subjective judgment on the operator's part, combined with the use of in-situ vision, process monitoring, laser monitoring, and post-process validation features, provides consistent production, increased yields, and reduced scrap. Whenever there is any deviation from the specified limits in the process, the machine makes the necessary adjustments or stops the process and alerts the operator. This is clearly a benefit for any application. It would be especially beneficial when welding p...
