Abstract :
A light source to drive the 1S0 - 3P0 transition in Yb atoms is generated by two solid state lasers: a Nd:YAG laser and a Yb:YAG laser, using a sum-frequency generation (SFG) scheme. With a ridge waveguide (WG) periodically poled lithium niobate (PPLN) device, SFG power of about 150 mW is obtained at the required frequency. The performance of the clock laser system is evaluated with studies of frequency stability measured by an optical frequency comb and with atomic absorption spectra of the 171Yb clock transition at 578 nm.
