Abstract
We have demonstrated Doppler-free intermodulated fluorescence spectroscopy of helium 23P–31,3D transitions in an rf-discharged sealed-off cell using a compact laser system at 588 nm. An external cavity diode laser at 1176 nm was constructed to seed a Raman fiber amplifier. Laser power of more than 1 W at 588 nm was produced by frequency doubling of the fiber amplifier output using a MgO:PPLN crystal. A doubling efficiency of 23 % was achieved. The power-dependent spectra of the 23P–33D transitions were investigated. Furthermore, the Doppler-free spectrum of the spin-forbidden 23P–31D transitions was observed for the first time. Our results are crucial toward precision test of QED atomic calculations, especially for improving the determination of the helium 31D–33D separation.
