Transmission of Gaussian Beam Through Graded-Index Slab I am new to this concept. Could you briefly show me how this would be done? |

Transmission of Gaussian Beam Through Graded-Index Slab I know that $\frac{-2i}{k W_2^{2}}$ can be expressed in terms of $\alpha, d, W_0, \lambda_0$. However, to get the full width function, I need to express the real part ($\frac{1}{R_2}$) in those terms as well, or get rid of it entirely. Could you please help me with that? |

Transmission of Gaussian Beam Through Graded-Index Slab The beam width function that I get must be a function of d, which means I cannot include $\frac{1}{R_2}$ in it. I then have to express $\frac{1}{R_2}$ in terms of $\alpha$, d, $W_0$, $\lambda_0$, or get rid of entirely. This is the part I'm unsure about. Is it possible that the beam leaves at its waist as well, allowing us to eliminate $\frac{1}{R_2}$? |

Transmission of Gaussian Beam Through Graded-Index Slab Thank you for your reply. Wouldn't it be $q1=-kW_0^{2}/(2i)$ though? And this would just give us an expression for q1, from which we can get an expression for q2. However, we still need to substitute out for q2, and to do this, we need to get the radius of curvature for the beam leaving the slab. I'm still not sure how to do this. |

Width of Gaussian Beam and Refractive Index Looks good. Could you take a look at my other question: physics.stackexchange.com/questions/38730/…, which is related to this one? |
