can someone help writing a python code for calculations like beam waist, diffraction losses, photon lifetime inside cavity?
I hope this helps :
import math
def beam_waist(w0, z, zr):
w = w0 * math.sqrt(1 + (z/zr)**2)
return w
def diffraction_loss(R, L):
loss = (1 - R) * L
return loss
def photon_lifetime(L, c, loss):
tau = (L/c) * (1/loss)
return tau
# Example usage
w0 = 1.0 # waist size at the laser's output
z = 2.0 # distance from the center of the cavity
zr = 3.0 # Rayleigh range of the beam
R = 0.9 # reflectivity of the cavity mirrors
L = 4.0 # length of the cavity
c = 3.0e8 # speed of light
beam_waist_result = beam_waist(w0, z, zr)
diffraction_loss_result = diffraction_loss(R, L)
photon_lifetime_result = photon_lifetime(L, c, diffraction_loss_result)
print(beam_waist_result)
print(diffraction_loss_result)
print(photon_lifetime_result)
