Shanghai Institute of Optics and Mechanics has made new progress in the creation mechanism and prediction of edge effects in digital ultra-precision sub-aperture polishing

The Center for Precision Optics Manufacturing and Testing, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences has made new progress in the creation mechanism and prediction of edge effects in digital ultra-precision sub-aperture polishing.

The research proves that the material removal mechanism of the tool obeys the ‘convolution’ operation rule when the edge is moving, and the concept of nonlinear edge convolution kernel is proposed for the first time, so that it can easily adapt to complex edge situations. At the same time, moment balance constraints and basic pressure distribution are proposed to quantitatively predict the pressure changes caused by tool linear tilt and tool unevenness.

The research results have improved the ability to predict and compensate for edge errors in optical processing, have important guiding significance for improving the quality of tool edge processing, and lay a foundation for the future development of intelligent optical manufacturing. The related results were published in Optics Express (“Optics Express”). (Click here to view the full text)

Shanghai Institute of Optics and Mechanics Achieves Breakthrough Progress in Miniaturized Free Electron Laser Research

The State Key Laboratory of High-Field Laser Physics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences has made a breakthrough in the research of miniaturized free electron lasers based on laser accelerators by using the self-developed ultra-intense and ultra-short laser devices with international leading comprehensive performance. .

By significantly improving the quality of the electron beam accelerated by the laser wake field, combined with an innovatively designed compact beam transmission and radiation system, the research team has experimentally realized the output of free electron laser amplification based on a laser accelerator for the first time. The typical laser wavelength is 27 nanometers. The wavelength of MIN laser can reach 10 nanometers, and the single pulse energy can reach 100 nanojoules. It is the first in the world to complete the experimental verification of the principle of desktop free electron lasers, which is of great significance for the development of miniaturized and low-cost free electron lasers.

What is “Rayleigh Scattering”

Rayleigh scattering is a scattering of light where the center of scattering is much smaller than the wavelength. Rayleigh scattering is a very common optical phenomenon named after the British physicist Earl Rayleigh. It is a linear scattering of light with a scattering center much smaller than the wavelength of the light. In this case, the scattered light amplitude is proportional to the incident light amplitude, the fourth power of the reciprocal wavelength, and 1?+?cos2?θ, where θ is the scattering angle. Forward and backscattering (θ?=?0 and θ?=?π, respectively) are usually equal. (Click here to view the full text)

【2021 Optical Software Recommended List】


Zemax is a comprehensive set of optical design software. It integrates all conceptual, design, optimization, analysis, tolerance analysis and documentation functions of an optical system. The new version of OpticStudio offers new diffraction calculations and two new tolerance setting operands. In OpticStudio 21.1, diffractive optics-related functions, which play an important role in the augmented reality and head-up Display markets, have been enhanced. This update also adds tolerance operands to help users better adjust designs based on true tolerances.

Photon Design

PhotonDesign is a set of excellent photonics, optical communication, waveguide optics series software, which is widely used in optical fiber communication system design and photonic device design. It has the advantages that other software can’t replace. It has powerful functions and can fully meet your design needs, including multiple functional modules.


ASLD is an efficient and easy-to-use solid-state laser resonator design and optimization simulation tool. It can range from pump system models to resonator simulations and the interplay between physical properties such as optical, mechanical, thermal effects, and electric fields within the system.

ASLD was designed with consideration in mind, and now it also has the function of analyzing the output power, multimode analysis and beam quality of continuous wavelength and pulsed lasers. The software can also accurately calculate the mechanical, optical and thermal lensing effects inside the laser crystal. Furthermore, ASLD includes powerful and efficient algorithms to accurately simulate the stability and output energy of the system resonator.

The graphical interface of ASLD allows users to directly insert components in the pump cavity or laser resonator, and define the structure and characteristic parameters of the optical components through the corresponding windows. And, the simulation data can be adjusted through the corresponding window. In this way, the operation of adjusting the component structure and parameters through the graphical interface can improve the system design efficiency.
