Question

Compute the Doppler broadening for the 632.8nm laser transition in the He-Ne laser, assuming a single isotope of Ne20 and that the laser operates at a discharge temperature of 200⁰C.
​

Answer 1

Answer:

Compute the Doppler broadening for the 632.8nm laser transition in the He-Ne laser, assuming a single isotope of Ne20 and that the laser operates at a discharge temperature of 200⁰C.

b. Calculate the width of the laser transition due to natural broadening assuming that the the pressure inside the cavity is 20 Torr and the transition probability is given in the table on the last page – Assume that the transition rate changes by a factor of 107 s -1Torr-1 .

c. Find the ratio of Dn (Natural) / Dn (Doppler)..
