Passage One
The "adaptive optical correction technology" has become a core breakthrough in high-precision laser applications, aiming to eliminate the influence of atmospheric turbulence or optical system aberrations on laser beam quality. Traditional laser systems often suffer from beam distortion—for example, a long-distance laser communication system once saw a 40% reduction in signal transmission efficiency due to uncorrected atmospheric turbulence, limiting its application in satellite-ground communication.
Researchers at the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics recently developed a "real-time wavefront sensing + deformable mirror" adaptive system. This system uses a high-speed wavefront sensor (sampling rate 1000 Hz) to detect beam distortion in real time and drives a deformable mirror to correct aberrations within 0.1 milliseconds. When applied to a 1064 nm solid-state laser system, the system reduced beam divergence angle by 60% and improved the laser’s focusing accuracy by 50% compared to traditional systems. Additionally, the system’s miniaturized design (volume reduced by 30%) enables its integration into portable laser devices, expanding its application in laser processing and remote sensing. This innovation not only solves the beam distortion problem of traditional laser systems but also provides a key technology for high-precision optical engineering.
- What is the key advantage of the "real-time wavefront sensing + deformable mirror" adaptive system?(2008 年中科院考博英语阅读题改编)
A. It reduces the cost of high-power laser components.
B. It eliminates beam distortion and improves laser application precision.
C. It eliminates the need for optical alignment in laser systems.
D. It shortens the development cycle of laser devices.
(1) The application of femtosecond laser technology in micro-nano processing is not only conducive to realizing the high-precision fabrication of complex optical structures but also plays a crucial role in promoting the innovation of optoelectronic device manufacturing.(2008 年中科院考博英语翻译题改编)

Advanced laser technologies, such as femtosecond lasers, adaptive optical lasers, and fiber lasers, have become core drivers for the innovation of optoelectronic engineering and precision manufacturing industries. By breaking through technical bottlenecks in high-precision processing, high-speed communication, and high-sensitivity detection, they bridge the gap between optical science and industrial application—a value fully demonstrated by the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics.
Firstly, in optoelectronic engineering, advanced lasers enable high-performance device fabrication. The institute’s femtosecond laser micro-nano processing technology achieves a processing resolution of 50 nm, realizing the precise fabrication of micro-lens arrays for optical communication modules. Applied to 5G optical transceivers, these arrays improve signal transmission bandwidth by 40% and reduce energy consumption by 25%, promoting the upgrade of optoelectronic communication systems. Additionally, the institute’s laser epitaxy technology for semiconductor materials reduces the defect density of optoelectronic chips by 60%, enhancing the luminous efficiency of laser diodes (LDs) by 30%.
Secondly, in precision manufacturing, advanced lasers improve processing accuracy and efficiency. The institute’s high-power fiber laser cutting system achieves a cutting precision of ±0.01 mm for metal sheets, 50% higher than traditional mechanical cutting. In the automotive industry, this system reduces the processing time of engine parts by 40% while improving the parts’ surface smoothness. Moreover, the institute’s laser welding technology for lithium-ion battery electrodes reduces the welding defect rate to less than 0.1%, ensuring the safety and service life of new energy vehicle batteries.
In conclusion, advanced laser technologies are indispensable for the development of optoelectronic engineering and precision manufacturing. For institutions like the CAS Shanghai Institute of Optics and Fine Mechanics, continuing to innovate laser technologies (e.g., integrating AI for adaptive control) will be crucial to supporting industrial upgrading and high-tech development.
