Frequency doubling of Telecom sources

 

Presentation

Telecom sources at 1560 nm, when frequency doubled, are convenient sources for manipulation of cold rubidium atoms, which resonant wavelength is 780 nm. We have built a source based on frequency doubling of a telecom diode, amplified to 10 W. We get 2 W of power at 780 nm. For more information on our frequency doubling set-up see our paper.
