Dear Colleagues,
We are trying to generate 1414 nm from 1064 nm by Stimulated Raman
Scattering in N2:He mixture. We are unable to separate the two
wavelengths by Pellin Broca prism even after 1 m distance. The incident
beam i.e. 1064 nm is dough-nut shaped. This while coming out of the raman
shifter appears as a full beam. We are sure that 1414 nm is generated
but we are bit perplexed regarding the separation of these two
wavelengths. (The pressure is 41 kg/cm2 and the incident power is 250
mJ/pulse). Kindly let us know the solution of this problem.
With warm regards,
Mily.
