Hi all,
I am interested in finding the power of a laser diode as function of the distance z, assuming a free space propagation. I think to have enough information to work it out but I am stacked at the moment.
Given:
Thanks in advance for any help!
I am interested in finding the power of a laser diode as function of the distance z, assuming a free space propagation. I think to have enough information to work it out but I am stacked at the moment.
Given:
- the initial power, P0 = 1mW
- beam width clip (e-2 = 13.5%), wx = 3μm, wy = 1μm
- wavelength, λ = 650nm
- divergence beam width (full angular), θ = 1mrad
- M2 = 5
Thanks in advance for any help!
