Laser wavelength in the condition of oblique incidence #545

Closed 2018-2025 closed 1 year ago

2018-2025 commented 1 year ago

I want to know the value of laser wavelength in the condition of oblique incidence. In the epoch_user.I note that a laser travelling at an angle to a boundary, the new wavelength to use will be λcosθ. Thus, should i use the value of λcosθ to instead of the value of λ?An example is provided below. lambda = las_lambda

lambda = las_lambda*cos(theta)

Which one is correct? image image
