Homework Statement


Handwritten worksheet of lens and beam calculations with columns of values for focal length, diameter and wavelength, plus a hand-drawn diagram of two parallel mirrors with a beam spot labelled.

Handwritten notes on paper: a sketch of a cylindrical lens with dimensions, a note that cylindrical lenses can only be mounted if the diameter exceeds a value, a diagram of a beam through a lens setup with labelled distances, and the words 'ANY SUGGESTIONS?' at the bottom.


Homework Equations


Lens equation
1/f = 1/d_o + 1/d_i

Minimum Gaussian beam spot
2*w_0 = ((4 * lamda * F)/(pi * D))

Where:
w_0 = beam waist (half beam diameter)
lambda = wavelength
F = focal length of lens
D = diameter of incoming spot

Don't forget to match units.

Let me know if you would like any clarifying questions. I wrote this problem out on paper and didn't want to type so I embedded images instead. I hope this isn't a problem.

P.S. distance between mirrors is 4 inches.

Thank you for any help

The images are too small to be read easily. Handwriting (particularly someone else's, is all but indecipherable at this resolution. Members using mobile devices won't have a hope of reading it, never mind referencing or quoting portions of it. Please type out your question and and attempt at solution and use images as supporting material.
