The code provides a template for data entry and plotting functions for laser and neutral density filter transmission. measurements of the fluence (energy per area). M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. The irradiance cross-section of Gaussian beams decreases symmetrically with increasing distance from the center; in contrast, flat-top beams, also known as top-hat beams, maintain a constant irradiance value through a beam Real-time focus finding with instant M². Does damage threshold depend on power Most laser beams have a Gaussian irradiance profile, although it can be beneficial to use a non-Gaussian beam in certain applications. The use of Matlab Laser Toolbox for commercial purposes is strictly prohibited. Reload to refresh your session. Introduction. Near the laser, known as the optical near-field, the beam is dominated by a disordered wavefront and the beam profile can change as it propagates along We have example MATLAB interfaces for WinCamD cameras as well as the BeamMap2 beam profiler to get you started. 3.
