Claim of US Patent No. 10,342,113

1. A method of generating a vapour of neutral atoms of a specific species, the method comprising the steps of:positioning a sample material comprising a compound of the specific species, in a vacuum; and
irradiating the compound with a first laser, thereby to generate a vapour of neutral atoms of the specific species from the compound of the specific species, wherein the neutral atoms of the specific species in the vapour of neutral atoms of the specific species have a velocity of less than 50 ms?1, and wherein a power output of the first laser is selected such that an intensity at the sample material is less than 4 kW/cm2.
