Abstract
The frequency of the output beam of a high power krypton fluoride laser is shifted by a plurality of Raman cells arranged successively in the path of the laser beams. These cells each contain a gas selected from the following gases: H.sub.2, HD, D.sub.2 and CH.sub.4, the combination of the gases used being chosen to provide a frequency shift of the beam so as to produce an output in the 330-355 nm range, which is suitable for use in photopredissociation of formaldehyde (HDCO) so as to produce heavy water (D.sub.2 O).
