We present a powerful new laser setup for light-induced manipulation of Lithium atoms which is currently being developed within the framework of the Fermix experiment at ENS.
The design is based on a diode-pumped solid state Nd:YVO4 ring laser, operating on the 4F3/2→ 4I13/2 transition near 1342 nm. The infrared light is subsequently frequency doubled to the Lithium-6 D2 resonance at 670.977 nm in an enhancement cavity using periodically poled Potassium Titanyl Phosphate (ppKTP). Hereby, a special locking technique is applied.
The results obtained so far indicate a higher performance in terms of power, spatial mode quality and simplicity compared to the existing laser sources in the same wavelength range.
