• Using a visible probe laser exciting the 2p^3P_2→^3d^3D_3 transition (λ=588 nm), we have demonstrated a visible observation of metastable He atoms magnetooptically trapped by an infrared laser resonant with the 2S^3S_1→2P^3P_2 transition (λ=1083nm). Detecting visible resonance fluorescence, only 10^4 atoms confined in a trap with a diameter of 1 mm have been sensitively observed even with the naked eye. It has been found that under a given condition the visible laser operates as a trapping laser and considerably extends the capture range of infrared laser detuning.
