The fast laser beam shaping (FLBS) simulation, commonly known as FLBSIM, is a computer simulation used to generate highly accurate laser beam structures and to rapidly optimize the characteristics of optical systems. FLBSIM technology is widely used to simulate and optimize the performance of any number of optical components, allowing for a wide range of applications and capabilities. This article will discuss the application fields and working principle of FLBSIM.

Application Fields

FLBSIM is used in many fields, such as design and manufacturing of optical system, optical tracking and pointing systems, optical beams combining systems, optical multiplexing systems, optical networking systems, optical communication systems, image processing systems, etc. FLBSIM technology may also be utilized for laser beam machining, beam steering systems, optical data communications, optical sensing and detection, beam manipulation, and many other applications. Additionally, laser-based analytical instrumentation may also use FLBSIM technology to aid in calibration and testing.

Laser beam shaping enables laser beams to be tailored for specific tasks such as laser beam cutting, laser drilling, laser welding, and many other laser applications. FLBSIM technology can also be used to create and modify a variety of beam profiles, inclinations, and angles for distinct applications. Furthermore, FLBSIM can be used to analyze laser properties such as laser power, divergence, far field size, pulse length, focal length, scan pattern, and many other laser characteristics.

Working Principle

FLBSIM digitally simulates the internal structure and behavior of a laser beam employing numerical methods and algorithms. These simulations can then be applied to a physical laser beam, replicating the effects of physically present elements on optical wavefronts such as laser aperture size, aperture distortion, absorption, scattering, phase, beam propagations, far field size, etc. The numerical simulations make use of convolution and two-dimensional Fourier transforms, which simulate the optical system in terms of lenses, diffraction gratings, and other components.

In addition, the numerical simulations may also be used to investigate the effects of the polarization state of the incoming light beam and of any spectral content of the light. The numerical feedback can allow engineers to rapidly adjust the optical setup to achieve regular, controllable, and repeatable optical performance. Furthermore, the simulations may also be used to retrieve the image of objects in the field of view, and subsequently enhance the resolution and contrast of the images.

The ability to simulate the behavior of complex optical systems utilizing the means of numerical forecasts allows engineers to reduce material costs while also optimizing the system. Additionally, by employing the numerical model, engineers can estimate the output field of view, beam shape, beam profiles, beam size, and many other factors. FLBSIM also enables the adjustment of numerous variables, including the size and shape of the laser beam aperture, angle of the input beam, optic element constant, optical element tilt, etc.

Overall, the fast laser beam shaping (FLBS) simulation (FLBSIM) is a powerful tool for simulating and optimizing the performance of any number of optical components. FLBSIM technology is widely used to simulate and optimize the performance of optical systems in many application fields, such as design and manufacturing of optical systems, optical tracking and pointing systems, optics beams combining systems, etc. Additionally, laser-based analytical instrumentation may also use FLBSIM technology to aid in calibration and testing. FLBSIM can enable engineers to reduce material costs while also optimizing the system and retrieving the image of objects in the field of view.
