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
