Abstract: Metal atoms in solid and liquid helium-4 have attracted some interest eitheras a way to keep the atoms in a weakly perturbing matrix, or using them as aprobe for the helium host medium. Laser sputtering with nanosecond pulsedlasers is the most often used method for atom production, resulting however ina substantial perturbation of the matrix. We show that a much weakerperturbation can be obtained by using femtosecond laser pulses with energy aslow as 10 $\mu$J. As an unexpected benefit, the atomic density produced is muchhigher.
