Description

Technical Field

[0001] The invention relates to a structural device and a working method integrating laser window pasting and bar array deflection detection, belonging to the technical field of laser packaging and detection. Background Art

[0002] Semiconductor lasers have become an indispensable part of modern laser technology due to their advantages such as miniaturization, high efficiency, fast response speed and relatively low price. They are widely used in communications, optical storage, laser printing and cutting, medical treatment, sensors, military and scientific research.

[0003] The windows of lasers are usually used to protect the optical elements and other components inside the lasers from external factors such as dust and moisture. In the production and maintenance process of lasers, the quality of the window pasting is crucial and directly affects the performance and service life of the laser. The commonly used method of pasting windows is adhesive technology: the use of adhesives to fix the windows requires the adhesives to have good thermal stability and light transmittance, and the effects of factors such as thermal expansion on the fixing effect need to be considered. Bar arrays are often used for arraying and combining lasers to achieve higher power and better beam quality. Skew detection is one of the important links to ensure the normal operation of the array.

[0004] With the continuous development of laser technology, especially in the field of high-power laser and precision optical applications, the requirements for the integration, stability and efficiency of laser equipment are getting higher and higher. Integrating the laser window pasting and the bar array deflection detection into an integrated structural device can effectively improve production efficiency, reduce manual intervention, and improve product consistency and reliability. Existing technical solutions usually handle window pasting and deflection detection separately, resulting in low production efficiency and potential quality problems. Summary of the invention
