WitrynaThe Gaussian quadrature chooses more suitable points instead, so even a linear function approximates the function better (the black dashed line). As the integrand is the polynomial of degree 3 ( y(x) = 7x3 – 8x2 – 3x + 3 ), the 2-point Gaussian quadrature rule even returns an exact result. In numerical analysis, a quadrature rule is an ...

"WitrynaTo achieve high output power and/or high efficiencies, laser systems are often designed to operate with either high-order or multiorder transverse modes. This comes at the expense of beam quality. Herein, a technique for converting the two lobes of a higher-order (Hermite-Gaussian TEM10) beam into two TEM00 beams is discussed. It is … " - Hermite–gaussian
